Abstract
PURPOSE:To prevent destruction of elements, by controlling the switching circuit so that peak levels of rise voltages at both ends of switching elements may be prevented from exceeding the rating of these switching elements. CONSTITUTION:The power source voltage formed by rectifying circuit 2 and smoothing capacitor 3 is applied across the anode and the cathode of gate controlled switch (GCS) 1 through choke coil 4. The series circuit of work coil 6 and capacitor 7 and damper diode 8 are inserted in parallel between the anode and the cathode of GCS 1. Further, the series circuit of capacitor 13 and resistance 14 is connected in parallel between the anode and the cathode of GCS 1, and the connection point for them is grounded through resistances 15 and 16. Capacitor 18 for hold is connected to the connection point of these resistance 15 and 16 through diode 17, and one end of this capacitor 18 is connected to the anode of diode 20 through emitter follower transistor 19, and the cathode of diode 20 is connected to control terminal 12 of VCO 9.
