Abstract
PURPOSE: To prevent power-supply shortage in a simple constitution by controlling a main transitor which is corrsponding to a photo-coupler to a non-conductive state by the conduction of said photo-coupler, and by controlling the main transistor which is corresponding to the photo-coupler to a conductive state by the non-conduction of said photo-coupler.
CONSTITUTION: Pulses from an appropriate pulse source PL are frequency-divided, and two signals, whose phases are 180° out of phase each other, are output from an FF circuit to output terminals Q and Q', from which the signals are input into the bases of switching transistors Tr1 and Tr2, respectively. Driving power supplies ES1 and ES2 are provided for main transistors Tr1 and Tr2, one end of the power supply ES1 is connected to the base of a main transistor TR1 through a base-current regulating resistor RB1 and Tr3, and the other end is connected to the emitter of the Tr1. A photo-transistor PTr1 is connected across the power supply ES1 and the collector of the PTr1 is connected to the base of the Tr3. The power supply ES2 is also connected to the main transistor Tr2 by the same method. In this constitution, power-supply shortage can be prevented beforehand.
