Abstract: A drive circuit for an electromagnetic brake is used in a circuit including a motor, a converter converting a DC voltage into an AC voltage to be generated between a pair of DC link buses, and an inverter converting the DC voltage into an AC voltage and driving the motor. A full-bridge circuit has a pair of power supply terminals connected to the pair of DC link buses, and a pair of output terminals connected to the electromagnetic brake.
