Title: Means for suppressing time rate of change of voltage in semiconductor switching applications
IPC: H03K17/72
Filed: 1968-06-15
Abstract: A circuit for suppressing the rate of change of voltage across a bidirectionally conductive switching means 13 comprising a semi-conductor controlled rectifier 20 and a rectifying element 21, such as a semi-conductor diode or further semi-conductor controlled rectifier, connected in inverse parallel, has a main suppressing circuit 22 connected directly across the parallel connection comprising a resistor 23 and capacitor 24 and an auxiliary suppressing circuit 25 comprising a resistor 26 and capacitor 27 is connected in parallel with the resistor 23. The voltage suppression circuit prevents the voltage across the thyristor 20 rising rapidly when it is switched OFF. When the current through the diode 21 stops a reverse recovery current of the diode starts and passes through the main suppression circuit 22 which adds to the initial anode voltage transient. In order to limit the excessive dv/dt an auxiliary circuit branch 25 is provided. The resistance of resistor 26 is lower than resistor 23 and the time constant of the auxiliary circuit 25 is made a small fraction, such as less than one-half, of the time constant of the main circuit. For the initial portion of the anode voltage transient on 20 the net resistance in series with capacitor 24 is lowered by the branch 25 to suppress the initial high dv/dt whereas during the remainder of the transient the effective resistance in series with capacitor 24 becomes increased to damp oscillations and limit voltage overshoot. The circuit may be used in an inverter the control means for triggering the switching means 13 and the particulars of the accompanying power components (rectifier, transformer complementary switching means) are not shown. A capacitor may be connected in series or parallel with the load 12.
