Definitions
- the invention relates to a current limiter with at least one semiconductor region with electron donor (source), electron collector (drain) and electrodes controlling the electron flow (gate).
- the disadvantage of mechanical protective switching devices is the wear of the contacts, frequent maintenance and a relatively slow switching time in the event of a short circuit, as well as a relatively low temporal accuracy of the switching time.
- Semiconductor switches can work without wear and switch quickly; they have low switching losses and they can be controlled variably. Disadvantages of semiconductor switches are: high costs, high space requirements and relatively high transmission losses.
- the object of the invention is to develop a current limiter using semiconductor technology, in which the disadvantages of the semiconductors which have been customary hitherto are reduced to a technically useful extent.
- a current limiter according to claim 1.
- the semiconductor region operates without its own control, and it has a characteristic curve such as that which field effect transistors (FETs) have.
- FETs field effect transistors
- a current interrupter device can be connected in series to the drain-source path be used in order to protect the semiconductor area as an overload relay or also to enable a shutdown during operation.
- the gate electrodes are dimensioned with respect to their thickness L, their distance d from one another and the source-drain path D in such a way that there is a limit at a given current strength.
- the gate electrodes are at floating potential, which is also known as "floating.” referred to as.
- the semiconductor region can be embodied integrated in a microchip or as a discrete component.
- a rapid short-circuit current limitation is achieved above an overload limit and thus equipment or electrical distributions can be protected quickly.
- circuit breakers the advantage of a strong and rapid current limitation is achieved, and the usual burn-up problems are avoided.
- a rapid high current limitation is achieved without affecting intact parallel circuits of a consumer network.
- PTC thermistors In comparison to PTC thermistors, a more stable characteristic is achieved.
- the semiconductor region may • be designed as a vertical "Junction” -Feld ⁇ effect transistor (J-FET). It is particularly advantageous to form the semiconductor region from a substrate material made of silicon carbide.
- this can be designed as a switch contact with a tripping device.
- the semiconductor region is designed with embedded gate electrodes.
- the semiconductor region can also be developed in such a way that gate electrodes are arranged on the source electrode and others on the drain electrode with an electrically conductive connection to the source or drain electrode.
- the drain-source path can then be compared to fully embedded gate electronics. which are roughly halved, with the operating conditions remaining the same.
- coolants on the source electrode and on the drain electrode which can be dimensioned such that the limiting current can be reduced in the current-time diagram as a result of a positive temperature coefficient which is established.
- Such a lowering is also advantageous for a semiconductor region which is operated as a unipolar component.
- the pn junction between the gate and the drain-source path then does not come into play as a diode, since the threshold voltage, for example 2.8 volts at SiC, is used. In other words: the permissible load current density remains below the diode pass characteristic. You then work in the ohmic area.
- FIG. 1 shows a first exemplary embodiment using a semiconductor region with embedded gate electrodes.
- 2 shows a current limiter as shown in FIG. 1 with a semiconductor region, the gate
- Has electrodes that are electrically connected to the source electrode and gate electrodes that are connected to the drain electrode. 3 shows a characteristic of the current limiter in a diagram, on the ordinate of which the drain-source current is plotted and on the abscissa of which the drain-source voltage is plotted.
- This diagram illustrates, by way of example, the mode of operation of a current limiter according to FIG. 1.
- FIG. 4 shows a diagram as shown in FIG. 3, which exemplifies the mode of operation of a current limiter according to FIG. 5 shows a characteristic curve in the current-time diagram for current limiters with additional developments.
- the semiconductor region is operated as a unipolar component or, or and, and coolants are used.
- FIG. 6 shows a current limiter according to FIG. 1 with coolants on drain and on source electrodes.
- FIG. 7 shows coolant in a current limiter according to FIG. 2.
- the current limiter according to FIG. 1 works with a semiconductor region 1, with source electrode, source electrode 2, drain electrode 3 and gate electrode 4.
- the gate electrode does not have its own control and is completely embedded.
- the gate electrode 4 can consist of individual doping islands or can also be produced from a disk-shaped doping region with hole-like interruptions.
- the gate electrodes 4 are dimensioned with respect to their thickness L, their distance d, from one another and the source-drain path D in such a way that a current limitation is established at a given current strength.
- the working range entered is obtained with a characteristic according to FIG. 3. Up to 230 volts one works in the linear range 8 and in the case of overvoltages up to about 700 V one remains in the horizontal limitation range, so that the current intensity I- Q is set independently of the voltage U D g.
- the linear region 8 corresponds to an ON resistance RON
- a current interrupter device 5 with a switch contact 6 can be connected in series with the drain-source path to the semiconductor region 1.
- the circuit breaker device 5 usually has a switch contact 6 with a tripping device 7.
- the current interrupter device 5 can act as an overload relay to protect the semiconductor area in the event of voltage 3, in which the characteristic curve for high drain-source voltages changes into a region parallel to the drain-source current.
- the current interrupter device 5 can also be designed for operational shutdown in order to achieve a current limiter with the properties of a circuit breaker, for example in the manner of a circuit breaker.
- the semiconductor region then works as a particularly good limiter, which makes it unnecessary to provide the current interrupter device with arc extinguishing devices.
- the semiconductor region can be understood as a vertical "junction" field effect transistor, J-FET. It is particularly favorable if the semiconductor region is formed from a substrate material made of silicon carbide.
- gate electrodes 4a are arranged on the source electrode 2 and other gate electrodes 4b on the drain electrode 3 and are connected in an electrically conductive manner to the source or drain electrode.
- the drain-source path can be shortened by approximately half and a steeper linear region 8 of the characteristic curve is obtained, which results in a lower ON resistance RON- * corresponds.
- the first and third quadrants are used, as illustrated in FIGS. 3 and 4.
- a semiconductor region with a structure according to FIG. 2 can thus be halved in comparison to a semiconductor region in the structure according to FIG.
