A method for dividing voltage stress of high voltage class E inverter

In this paper, splitting of peak switch voltage by series connected transistors in the class E inverter is proposed. In this method, peak switch voltage of class E inverter is reduced to half of conventional because shunt capacitor voltage is divided by two switches. Key feature of this method is that drive signal source of each switch can be grounded. Namely, transformer is not required in this method even though the source port of the series connected transistor is not grounded.
