Abstract

PURPOSE: To suppress overcurrents due to incompatibility of the phase of gate pulses and motor counter emf, by attaching a bias-regulating circuit, a sensor for sensing motor-rotating direction, and a sensor for converter operation to a Leonard control circuit.
CONSTITUTION: A motor M is connected to thyristors 100, which are connected in counter-parallel, and controlled by a Leonard control device 200 having a speed- regulating circuit, a current control circuit, a gate-phase control circuit, and an operating thyrister sensor. A sensor 400 for sensing the rotating direction of the motor M and a sensor 500 for converter operation are provided. And also is provided a bias regulating circuit 300 which gives bias to that the potential level of the armature counter emf and the converter output voltage become equal when both thyristors A and B are nonconductive. In this constitution, the potential difference due to incompatibility of the phase angle of the gate pulses and the counter emf can be eliminated, the overcurrent can be suppressed, and the device is protected.
