PLL controller for achieving zero-voltage switching (ZVS) in inductorless half-bridge drive piezoelectric transformer resonant power supplies

PLL controller for achieving zero-voltage switching (ZVS) in inductorless half-bridge drive piezoelectric transformer resonant power supplies

Inductorless half-bridge, piezoelectric transformer (PT) resonant power supplies require careful control if zero-voltage switching (ZVS) of the MOSFETs is to be achieved. Here, the authors describe how a phase-locked loop (PLL) may be used to achieve this...
