Abstract
A driving device is provided. The driving device includes a boost inductor and a resonance circuit. The boost inductor receives a first power via a first terminal of the boost inductor in a first mode and provides a second power via a second terminal of the boost inductor. The resonance circuit stores a stored electric energy from the second power in the first mode, so that the boost inductor does not provide the second power in the second mode and drives a transducer by the stored electric energy in the first mode and the second mode.
Claims10
A driving device, adapted to drive a transducer, comprising:
- a boost inductor, configured to receive a first power via a first terminal of the boost inductor in a first mode and provide a second power via a second terminal of the boost inductor;
- a rectifying circuit, coupled to the second terminal of the boost inductor and configured to limit a transmission path of the second power;
- and
- a resonance circuit, coupled to the transducer and the rectifying circuit, and configured to store a stored electric energy from the second power in the first mode, so that the boost inductor does not provide the second power in a second mode and drives the transducer by the stored electric energy in the first mode and the second mode, wherein the first mode and the second mode are alternately operated.
