摘要： A switching signal generator outputs a switching signal which indicates either an accelerating mode or a decelerating mode by comparing a motor control signal and reference voltage. A first activation signal generator and a second activation signal generator output a first activation signal and a second activation signal, respectively, according to the switching signal from the switching signal generator. A switching control signal generator outputs either a switching control signal based on a motor location signal or a desired electric potential according to the switching signal from switching signal generator, a first activation signal from the first activation signal generator and a motor location signal. When a power-supply side controller and an earth side controller are in a decelerating mode, power-supply side first, second, and third output transistors are non-conductive and first second and third earth side output transistors are conductive by supplying a base current based on a predetermined electric potential from the switching control signal generator.
