Improved ZVS Criterion for Series Resonant Converters
Zero voltage switching (ZVS) of power MOSFETs is essential for resonant converters and the ZVS criterion should be formulated appropriately to achieve the ZVS condition. Conventionally, the energy-based criterion has been considered the most accurate ZVS
