This paper explores the design of Novel Auxiliary switch dc-dc boost power converter operating in the Very High Frequency range
.
The main switch and auxiliary switch operate at zero-current-switching (ZCS) 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.These methods are applied to the development of a 26W resonant boost converter operating at a switching frequency of 30MHz. Design of power stage, hardware design procedure, simulation result and hardware results are treated in detail. For demonstration, a prototype Novel Auxiliary switch system is designed and implemented with discrete components to deliver 26W peak power with 88.9% of efficiency.
