Analysis and design of a 30 MHz resonant boost converter

This paper presents the analysis and design procedure of a Zero Voltage Switching (ZVS) resonant Boost converter operating at 30 MHz under hysteretic control (also called on-off control or bang-bang control). The Boost converter is based on the Class Φ inverter and combined with a class E rectifier. A multi-stage resonant gate driver is used to drive the power MOSFET effectively. The power train, gate dive and control design are provided in detail respectively. The design considerations are presented based on the efficiency optimization between the high component stress and the effect of parasitic parameters. The simulation results of the 30 MHz resonant Boost converter are given to verify the validity of the design method. An experimental prototype is being built.
