Dynamic analysis of class E resonant DC-DC converter regulated under fixed switching frequency

An averaging circuit model is developed for the class-E resonant DC-DC converter regulated at a fixed switching frequency. The regulation is achieved by use of an auxiliary switch. The model is obtained based on the circuit analysis using the Fourier series expansion, with only DC and fundamental components considered. Small-signal dynamic analysis is presented, which reveals that there exists a right-half-plane zero in the control-to-output transfer function. The analytical results are verified by experiments
