Abstract
A drive circuit comprising: a direct current power source; a control unit for supplying control signals; a power switch topology comprising a first switch and a second switch each having an input terminal, an output terminal, and a control terminal, the input terminals being respectively connected to the power source, the control terminals being connected to the control unit for receiving the control signals there from, the output terminals being connected to a node; and an inductance connected with a capacitive load in series between the node and the power source, wherein the control signals control the switches to alternately conduct to thereby cause the node to output a pulse signal.
