SWITCH CIRCUIT
摘要:
The present invention is a switch circuit equipped with a first switch connected between another end of an inductive load having a one end connected to a one end of a DC power supply and another end of the DC power supply, a capacitor connected between the another end of the inductive load and the another end of the DC power supply and connected in parallel with the first switch, a second switch that connects the another end of the inductive load and the capacitor, a third switch that connects a one end of the capacitor on an inductive load side to the one end of the inductive load so as to be parallel to the second switch, and a control circuit that turns ON the second switch before the first switch is turned OFF and turns OFF the second switch before the first switch is turned ON after being turned OFF.
