Abstract

PURPOSE:To prevent overheating the winding by turning off the unilateral semiconductor switches for a specific time only after turning off the two-way semiconductor switches for AC current supply in the time of braking. CONSTITUTION:A driving circuit for an induction motor 2 is connected to AC power source 11 through the triode AC switches 4-5 respectively as the two- way semiconductor switches on the both ends of the induction motor 2, and it is constituted by providing in parallel an all wave rectifier circuit 6 consisting of a diode bridge circuit, the resistors 10(a)-10(b) and the thyristors 8-9 as the unilateral semiconductor switches. And, at the operation mode, the thyristors 8-9 are turned off, and AC current is supplied to an induction motor 3 through the triode AC switches 4-5. After turning off the triode AC switches 4-5, the thyristors 8-9 are turned off, and enter into the braking mode. As the result, AC current is supplied from the all wave rectifier circuit 6 for a specific time only, and braking effect increases.
