The paper introduces the detailed derivation and design procedure for class-E DC-DC converters operated at very high frequency. Design formulae of the converter are derived. The converter features zero or low dv/dt at the turn-on and turn-off instants of the switch in the inverter and the diode in the rectifier. Hence, it greatly alleviates the adverse effects caused by the parasitic inductance and capacitance from circuits and components. The circuit of the converter is typically non-linear and very complicated. Therefore, it is very difficult or impossible to analyze the converter directly, and an appropriate simplification analysis is required. Because the resonant frequency of the rectifier is very near to the switching frequency of the inverter and the LC tank of the rectifier has an enough high Q, these two conditions guarantee the converter can be divided into two independent parts, which do not influence each other. Based on that, the inverter and the rectifier can be analyzed and designed respectively. To verify the proposed converter and design method, a converter operated at 50 MHz is designed and simulated. The simulation waveforms are in close agreement with the results from the analysis, and validate the proposed design method is feasible and effective.
