用于高效压电变压器驱动的谐波消除压电滤波模块

Switching driving, such as pulse width modulation, has been used in many power circuits because of its high efficiency. However, given the capacitance of a piezoelectric transformer (PT) for high harmonics in a square waveform, using switching technology directly in a driver circuit is difficult without an inductance linked with the PT. This paper proposes a design of a piezoelectric filter module...
