Abstract |
This paper describes analysis and design procedure of an interleaved, self-oscillating resonant SEPICconverter, suitable for operation at very high frequencies (VHF) ranging from 30 MHz to 300 MHz.The presented circuit consists of two resonant SEPIC DC-DC converters, and a capacitive interconnection network between the switches which provides self-oscillating and interleaved operation. A designapproach to ensure zero voltage switching (ZVS) condition of the MOSFET devices is provided.To verify the proposed method, a 11 W, 50 MHz prototype was built using low-cost VDMOS devicesand experimental results are presented. Peak achieved efficiency was 87\%. |
