High-accuracy modelling of ZVS energy loss in advanced power transistors
Two simulation approaches for prediction of energy loss in high-voltage power transistors (∼600V) operating under ZVS (Zero-Voltage-Switching) and near-ZVS conditions are presented and proved by experiment in this work. The first approach is based on finite-element simulation whereas the second one...

Summary: | Two simulation approaches for prediction of energy loss in high-voltage power transistors (∼600V) operating under ZVS (Zero-Voltage-Switching) and near-ZVS conditions are presented and proved by experiment in this work. The first approach is based on finite-element simulation whereas the second one proposes a new SPICE model. Different from prior works, both models feature COSS hysteresis and related energy loss, thus showing high precision in replicating waveforms and energy loss for real tests in the primary-side of LLC resonant converters. |
