A family of compensation topologies for capacitive power transfer converters for wireless electric vehicle charger
TL;DR: A parameter tuning method is proposed to realize primary zero-voltage switching by adjusting the parameter of the double-sided inductor-capacitor-inductor-Capacitor compensation topology, and experiments show that the prototype achieves constant-current output and zero- voltage switching when the coupling capacitance varies.
