[Embodiment 2]

Fig. 6 is a circuit configuration diagram of the induction heating conditioner of the second embodiment. The same portions as those in Fig. 1 of the first embodiment are denoted by the same reference numerals and will not be described.

In Fig. 6, the point different from Fig. 1 is that a second upper and lower arm 4 is connected between the positive electrode and the negative electrode of the direct current power source 1, and the second upper and lower arms 4 are connected with power semiconductor switching elements 5c and 5d in series. First upper and lower arms 3 is connected to the second resonant load circuit 60 between the output terminals of the second upper and lower arms 4, and the second resonant load circuit 60 is composed of a heating coil 11 and a second resonant capacitor 13 connected in series. In the switching elements 5c and 5d, the diodes 6c and 6d are connected in parallel in the reverse direction. Further, snubber capacitors 7c and 7d are connected in parallel to the switching elements 5c and 5d.

Here, since the heating coil 11 and the object to be heated (not shown) are magnetically coupled, when the object to be heated is converted into an equivalent circuit viewed from the side of the heating coil 11, the object to be heated is formed. The effective resistor and the equivalent inductance are connected in series. The equivalent resistance and the equivalent inductance vary depending on the material of the object to be heated. Non-magnetic and low-resistance copper or aluminum is the equivalent of the equivalent resistance and the equivalent inductance. The magnetic body and the high-resistance iron When is the side getting bigger. Since the heating power of the object to be heated is proportional to the skin resistance and the magnetism, in order to heat the non-magnetic body, it is necessary to increase the frequency and increase the magnetic force. The method of increasing the magnetic force is a method of increasing the current and a method of increasing the number of coils of the heating coil 11, but since the loss of the circuit is proportional to the power of 2, the increase of the current is not a countermeasure. Thus, a method of increasing the number of windings of the heating coil 11 is taken. However, in the object to be heated of the magnetic material, since the original electric resistance is large, when the number of windings is increased by the non-magnetic object to be heated, the equivalent resistance is increased, and it is difficult for the current to flow in the resonance load circuit. In this embodiment, the inverter is configured as a full bridge type, and the output voltage can be increased. Therefore, the desired power can be supplied even to the object to be heated of the magnetic body.

Next, the operation will be described using FIG. 7 and FIG. 8. Fig. 7 and Fig. 8 show the open and closed states of the respective elements of the embodiment. In Figure 7, The switching element 5a of the first upper and lower arms 3 and the switching element 5d of the second upper and lower arms 4 are simultaneously turned on, and the switching elements 5b of the first upper and lower arms 3 and the switching elements 5c of the second upper and lower arms 4 are simultaneously turned on. During the state, an AC voltage of a switching frequency is applied to the resonance load circuit 60, and a high-frequency current flows in the heating coil 11 to perform induction heating. That is, induction heating is performed by a full bridging action. Further, the relay 19 is in an open state, and a high-frequency voltage is applied to the plasma generating portion 70 by the complementary driving of the switching elements 5a and 5b of the first upper and lower arms 3, thereby generating plasma. That is, plasma generation is performed by a half bridge operation. Here, as a method of controlling the induction heating power, generally, pulse frequency control (PFM) which can make the inverter easy to soft-switch operation is possible. However, in the present embodiment, in order to simultaneously generate plasma, it is preferable to A phase shift control in which the upper and lower arms 3 and the second upper and lower arms 4 are phase-shifted to drive. That is, the switching elements 5a and 5b of the first upper and lower arms 3 are set to have a dead time to be driven by an opening time Duty of approximately 50%, whereby the voltage applied to the plasma generating portion 70 is irrelevant induction heating power, and can be formed. for sure.

Next, the description is related to Figure 8. In FIG. 8, the switching elements 5c, 5d of the second upper and lower arms 4 are all in a closed state, and an alternating voltage is not applied to the resonant load circuit 60. Therefore, high-frequency current does not flow in the heating coil 11, and induction heating is not performed. On the other hand, when the relay 19 is in the on state, the high frequency voltage is applied to the plasma generating unit 70 by the complementary driving of the switching elements 5a and 5b of the first upper and lower arms 3, and thus plasma is generated. Further, the amount of plasma generated can be easily controlled by the pulse frequency control or the pulse amplitude control of the first upper and lower arms 3.

As described above, in the present embodiment, even in consideration of the condition that the number of windings of the heating coil 11 is increased by the non-magnetic object to be heated, the object to be heated can be supplied to the magnetic body by forming the inverter in a full bridge configuration. The power that is expected. Further, as long as the second upper and lower arms 4 are closed, the induction heating operation can be stopped, and only the first upper and lower arms 3 can be driven to generate only plasma.

[Example 3]

Fig. 9 is a circuit configuration diagram of an induction heating conditioner of a third embodiment. The same portions as those of the foregoing embodiments are denoted by the same reference numerals, and the description thereof will be omitted.

In FIG. 9, a first upper and lower arms 3 in which power semiconductor switching elements 5a and 5b are connected in series, and a second upper and lower arms in which power semiconductor switching elements 5c and 5d are connected in series are connected between the positive electrode and the negative electrode of the direct current power source 1. 4. In the switching elements 5a to 5d, the diodes 6a to 6d are connected in parallel in the reverse direction. The snubber capacitors 7a to 7d are connected in parallel to the switching elements 5a to 5d. The output terminal of the first upper and lower arms 3 is one end to which the heating coil 11 is connected, and the first resonant capacitor 12 is connected between the other end of the heating coil 11 and the negative electrode of the DC power source 1 to constitute the first resonant load circuit 50. . Further, a series circuit in which the second resonance capacitor 13 and the relay 20 are connected is provided between the other end of the heating coil 11 and the output terminal of the second upper and lower arms. The second resonance load circuit 60 is configured by the heating coil 11 and the first resonance capacitor 12 and the second resonance capacitor 13, and the relay 20 is switched in accordance with the material of the object to be heated or the set heating power, whereby the first resonance can be switched. The load circuit 50 and the second resonance load circuit 60. 9 is a circuit in which the series circuit of the heating coil 11 and the first resonance capacitor 12 is provided between the output terminal of the first upper and lower arms 3 and the negative electrode of the DC power supply 1, but may be provided at the output of the first upper and lower arms 3. The terminal is between the positive electrode of the DC power source 1. The output terminal of the second upper and lower arms 4 is one end to which the inductor 22 is connected, and the plasma generating portion 70 is connected via the relay 19 between the other end of the inductor 22 and the negative electrode of the DC power source 1.

Next, the operation will be described using FIG. 10 to FIG. 10 to 12 show the open and closed states of the respective elements of the embodiment. When the object to be heated is iron, as shown in FIG. 10, the relay 20 is turned on to reverse the full bridge by the first and second upper and lower arms and the heating coil 11 and the first and second resonance capacitors 12 and 13. The phaser is used for heating. As described above, since the magnetic material and the high-resistance object are large in equivalent resistance, current is hard to flow in the resonance load circuit. Therefore, by switching to the full bridge mode, the output voltage of the inverter is increased by 2 times compared with the half bridge mode, and the desired output is obtained.

In the case of iron, since the original resistance is large, the first and second upper and lower arms are driven at a frequency of about 20 kHz. When the relay 19 is in the on state, the high frequency voltage is applied to the plasma generating unit 70 by the complementary driving of the switching elements 5c and 5d of the second upper and lower arms 4, and thus plasma is generated. That is, plasma generation is performed by the half bridge operation of the second upper and lower arms 4. Further, as a method of controlling the induction heating power, it is preferable to provide a phase shift control in which the phase difference is driven by the first upper and lower arms 3 and the second upper and lower arms 4 in the same manner as described above. Here, the switching elements 5c and 5d of the second upper and lower arms 4 are provided with no load The time is driven by the opening time Duty of approximately 50%, whereby the voltage applied to the plasma generating portion 70 is constant regardless of the induction heating power.

When the object to be heated is copper or aluminum, as shown in Fig. 11, the relay 20 is turned off, and the inverter is heated by a half bridge type inverter composed of the first upper and lower arms 3, the heating coil 11 and the first resonance capacitor 12. . The skin resistance of the object to be heated has a characteristic of being proportional to the square root of the frequency, and it is effective to increase the frequency when heating a low-resistance object such as copper or aluminum. Therefore, the capacitance of the first resonance capacitor 12 is set such that the first upper and lower arms 3 can be driven at a frequency of, for example, about 90 kHz. Thus, the capacitance of the first resonance capacitor 12 is set with a drive frequency of about 90 kHz, but the capacitance of the second resonance capacitor 13 is set with a drive frequency of about 20 kHz. Since the driving frequency is greatly different, the capacitance of the second resonance capacitor 13 is formed to be sufficiently larger than the first resonance capacitor 12. Therefore, the resonant frequency of the inverter of the full bridge mode is mainly set by the second resonant capacitor 13.

In the second embodiment, the resonance capacitor is fixed, and the setting range of the drive frequency is limited. However, in the present embodiment, the capacitance of the resonance capacitor can be switched by switching of the relay 20. In this way, the setting range of the driving frequency of the inverter can be increased, and the material of the object to be heated can be used to heat at an optimum frequency. When the relay 19 is in the on state, the high frequency voltage is applied to the plasma generating portion 70 by the complementary driving of the switching elements 5c and 5d of the second upper and lower arms 4, thereby generating plasma. That is, when the object to be heated is copper or aluminum, it is half bridged by the second upper and lower arms 4. Make plasma generation. For this reason, it can be driven at a frequency independent of the induction heating operation, and therefore can be driven at a frequency suitable for plasma generation. This embodiment drives the second upper and lower arms 4 at a frequency higher than the frequency at which induction heating is performed. Further, the amount of plasma generated can be easily controlled by the pulse frequency control or the pulse amplitude control of the second upper and lower arms 4.

In the present embodiment, when the induction heating operation is stopped and only the plasma generation is performed, as shown in FIG. 12, the upper and lower arms 3 are turned off, and the relay 19 is turned on, and only the second upper and lower arms 4 are provided. You can do half bridge operation. Further, it is preferable that the relay 20 is in a closed state, but even if it is in an open state, as long as the series capacitance of the resonance capacitors 12, 13 is only connected in parallel to the snubber capacitor 7d, the series capacitance is sufficiently smaller than the snubber capacitor 7d, which is not a problem.
