Abstract

PURPOSE:To absorb the back power generated in inductance load by a simple circuit by mounting a back power voltage detecting circuit connected in parallel with load and a thyristor turned-ON by the output. CONSTITUTION:ON-OFF signals S3 are given to a system to be driven 9 containing a transistor, and a DC motor 7 as the inductance load is driven. In this case, the series circuit of a switch element 6 consisting of a thyristor and a resistor 8 is connected at both ends of the motor 7 while the back power voltage detecting circuit 6' composed of a Zener diode RD, a capacitor C1 and a resistor R1 is mounted. Accordingly, the Zener diode RD is operated through the inversion of the polarity of the inductance load when the ON-OFF signals 3 are at OFF, the switch element 6 is at ON, and the back power is absorbed by the resistor 8, thus having an effect by the simple circuit.
