Abstract
A drive circuit, an electronic device, and a method of controlling a drive circuit that can reduce power consumption. The drive circuit includes: a control circuit that controls application of an AC voltage to a capacitive load; an inductive element which constitutes a closed circuit along with the capacitive load; a diode , which is connected in series to the inductive element between the capacitive load and the inductive element so as to constitute the closed circuit; and a switch element, which is connected in series to the diode between the capacitive load and the inductive element so as to constitute the closed circuit.
