摘要： During PWM control in which an actuator (9) is connected between the output terminals of a bridge circuit made up of switching elements (121, 122, 221, 222) and power is applied to the actuator (9) with signals G1U, G1L, G2U and G2L, driving timing signals are generated with a time interval (dead time) during which the switching elements (121, 122) and the switching elements (221, 222) are simultaneously turned off, and the actuator (9) is driven so as to have no overlapping dead time between a pair of half-bridge circuits, achieving response even with a differential input PWM signal (S51-S52) having a small time difference.
