一种基于无杂散压电谐振器的3.2 kW电动汽车车载充电器DC-DC变换器

Piezoelectric power conversion has emerged as a promising technology for power-dense, efficient dc–dc conversion absent of magnetic components for energy storage. However, two practical challenges of piezoelectric devices have limited prototype demonstrations to relatively low power. First, spurious resonant modes plague low impedance resonator design, restricting operating load range, and lowerin...
