Why using newer Si SJ MOSFETs may not be a good idea for high frequency switching
Key Takeaways: Output capacitance Coss related loss is the major switching loss in resonant soft switching.New generations of silicon super junction MOSFETs (SJ MOSFETs) dissipate more energy per switching cycle than legacy ones.Hysteresis of new generations of silicon super junction is larger and increases with increasing dV/dt and peak Vds.Resonant switching techniques are used to reduce
