Definitions
- T is a transformer, in which a first switch circuit S1 and an input power supply E are connected in series to a series circuit of a primary winding T1 and an inductor L, and a second switch circuit S2 and a capacitor Are connected in parallel with the series circuit of the primary winding T1 and the inductor L.
- the secondary winding T2 of the transformer T is provided with a rectifying smoothing circuit including a rectifying diode Ds and a smoothing capacitor Co.
- a capacitor Cs is connected in parallel to the secondary-side rectifier diode Ds.
- the detection circuit 14 detects the output voltage Vo supplied to the load and, if necessary, the output current Io.
- a fourth capacitor Ci connected to apply a voltage to the winding Lp, a fifth capacitor Cr forming a closed loop together with the first inductor Lr, the primary winding Lp, and the second switch circuit S2, It is characterized by including switching control circuits SCI and SC2 that alternately drive the first and second switch elements on and off with a period during which both switch elements are off.
- the third capacitor Ca constitutes a low-pass filter or a part of the low-pass filter that cuts off the current of the harmonic component. It is characterized by that! /
- the first switch element Q1 and the second switch element Q2 perform a zero-voltage switching operation, so that switching loss is greatly reduced. Also, since the input half-wave rectified voltage or full-wave rectified voltage is switched to flow a current proportional to the rectified voltage, the peak value of the current becomes a sine wave, and a high power factor is obtained.
- the third diode Di which blocks reverse current to the second inductor Li, rectifies only the switching current that does not need to perform both rectification of the commercial AC voltage and rectification of the switching current as in Patent Document 3. As a result, the high-speed switching function can be satisfied and low-loss switching can be achieved. Further, since the high-frequency current does not flow through the diode for rectifying the commercial AC voltage in the input-side rectifier circuit Da as in Patent Document 3, the harmonic current suppressing function does not deteriorate.
- the fifth capacitor Cr that forms a series circuit connected to both ends of the first switch circuit S1 with the second switch circuit S2, and the first and second capacitors
- the fifth capacitor Cr is increased by increasing the voltage applied to the fifth capacitor Cr. Cr capacity can be reduced.
- FIG. 3 is a diagram showing an input voltage, an input current, and a current waveform flowing through an inductor.
- Trl Tr2—Transistor
- FIG. 1 is a circuit diagram of a switching power supply.
- Vin is a commercial AC power supply.
- the input side rectifier circuit Da is composed of a diode bridge and rectifies full-wave commercial AC power supply Vin via the EMI filter EMI-F.
- the first switch circuit S1 includes a first switch element Ql, a first diode Dl, and a first capacitor Cdsl.
- the second switch circuit S2 includes a second switch element Q2, a second diode D2, and a second capacitor Cds2.
- These diodes Dl and D2 are parasitic diodes of the switch elements Ql and Q2 which are FETs, and the capacitors Cdsl and Cds2 are parasitic capacitors of Ql and Q2.
- Q1 and Q2 are different. DJ, D2, Cdsl and Cds2 may be added to IJ.
- FIG. 2 is a waveform diagram of each part in FIG.
- FIG. 3 is a schematic waveform diagram of the input voltage Vin of the commercial power supply, the input current iin, and the current il flowing through the inductor Li.
- the on / off signals (gate-source voltage) of the switch elements Ql and Q2 are Vgsl, Vgs2, the drain-source voltage is Vdsl, Vds2, the drain current is idl, id2, the current of the rectifier diode Ds is is, and the inductor Li is Li.
- the current flowing is il and the exciting current of the transformer T is im, and the operation in each state is shown.
- FIG. 4 is a circuit diagram thereof. Unlike the switching power supply device shown in FIG. 1, in this example, a series circuit of a second switch circuit S2 and a fifth capacitor Cr is connected in parallel to the first switch circuit S1. Other configurations are the same as those shown in FIG. In FIG. 4, the drive windings Lb1 and Lb2 of the transformer T and the feedback circuits FBI and FB2 are not shown. Further, the switching control circuits SCI and SC2 are represented by blocks.
- the transformer T may be demagnetized because the current that charges the capacitor Ci passes through the transformer T when the voltage across the capacitor Ci is smaller than the voltage across the capacitor Ca.
- the diode Db is provided as shown in FIG. 1, the above-mentioned problem does not occur because the capacitor Ci can be directly charged at the time of startup or heavy load.

- a rectifier circuit Ds2 is provided between the output winding Lo of the second transformer T2 and the rectifier smoothing circuit RS.
- Other parts are the same as those shown in FIG. Note that the equivalent to the diode Db in FIG. 1 is not shown in FIG.
