Extended ZVS/ZCS operation of Class-E Inverter for Capacitive Wireless Power Transfer

In this work, a control strategy for a Class-E inverter for Capacitive Wireless Power Transfer (CWPT) application is proposed. The presented approach allows to stabilize the output power regulating the components values of the resonant tank. A matrix of capacitors is used to adjust the values of capacitances and the magnetic design procedure for the variable inductor is proposed. The obtained performances are evaluated through Plecs simulations and compared with the case without a control strategy.
