Driving circuit with energy recycle capability
A bidirectional charging and discharging circuit is coupled between a voltage source and a capacitive load and configured to drive the capacitive load. The bidirectional charging and discharging circuit includes a first switch, comprising a first terminal coupled to the voltage source; a second switch, comprising a first terminal coupled to a second terminal of the first switch, and a second terminal coupled to a ground; an inductor, comprising a first terminal coupled to the second terminal of the first switch and the first terminal of the second switch; a third switch, comprising a first terminal coupled to a second terminal of the inductor, and a second terminal coupled to a first terminal of the capacitive load; and a fourth switch, comprising a first terminal coupled to the second terminal of the inductor and the first terminal of the third switch, and a second terminal coupled to a ground.
