Abstract


This paper explores the design of Auxiliary switch resonant dc-dc boost power converter operating in the Very High Frequency (VHF, 30–50 MHz) range. The proposed design futures low current stress, low voltage stress and high efficiency over wide load range. The main switch and auxiliary switch operate at zero-current-switching (ZCS) turn on and turn off, and all passive semiconductor devices in this converter operate at zero-voltage-switching (ZVS) turn on and turn off. Besides operating at constant frequency and reducing commutation losses, this new converter have no additional current stress and conduction loss in the main switch in comparison to the hard switching converter counterpart. The methods are presented for assessment and comparison of results in VHF operation under soft switching and soft gating conditions. These methods are applied to the development of a 26W resonant boost converter operating at a switching frequency of 30MHz. Design of power stage, resonant gate drive, hardware design procedure ,simulation result and hardware results are treated in detail. For demonstration, a prototype Novel Auxiliary switch system was designed and implemented with discrete components to deliver 26W peak power with 88.9% of efficiency.
