Patent number: 9093947Abstract: A zero-voltage-switching (ZVS) piezoelectric driving circuit, suitable for use in a switching type power converter. It receives an input DC voltage from a half-bridge driving circuit, and through switching of an high-side switch set and a low-side switch set of the half-bridge driving circuit, converts it to an AC voltage and provides it to a piezoelectric element to drive a load. Wherein, a shunt circuit is connected electrically between the half-bridge driving circuit and the piezoelectric element for zero-voltage-switching (ZVS). Namely, when the high-side switch set and the low-side switch set are both switched off, the shunt circuit resonates with its parasitic capacitance, so that the high-side switch set and the low-side switch set perform ZVS, thus realizing ZVS in a wide range of frequency and a large range of load.Type: GrantFiled: December 28, 2012Date of Patent: July 28, 2015Assignees: MIDAS WEI TRADING CO., LTD., CHAMPION ELITE COMPANY LIMITEDInventors: Tao-Chin Wei, Yuan-Ping Liu
