Abstract
PURPOSE:To reduce power consumption due to circulating current, by providing a control function capable of stopping the circulating current. CONSTITUTION:By detecting with a logic circuit 24 that a load coil current's direction has been reversed and also by detecting with a logic circuit 21 that voltage has become lower than a preset voltage, bypass pair command signal is sent to a phase control circuit 11 by a logic circuit 25 under AND condition of the logic circuits. And then, a command signal which makes circulating current base zero or negative value is sent to a function generating circuit 8. When the circulating current stopped, a gate block signal is sent to a phase control circuit 12.
