Absorber for regenerative power of transistor inverter

Abstract

Abstract PURPOSE:To stabilize the operation of a circuit by giving a comparator comparing regtenerative voltage and AC rectified voltage hysteresis characteristics. CONSTITUTION:Capacitors C1, C2 are charged by amain circuit voltage rectified by diodes D1-D6. A DC motor M is driven by controlling transistors TR1-TR4. A comparator OP1 has hysteresis characteristics, compares regtenerative voltage and AC rectified voltage and controls a transistor R5 for absorbing regenerative power by its own output. A resistor R2 for absorbing regenerative power is connected in series with the transistor TR5 for absorbing regenerative power.
