The Design of Phase Shift Soft Switching Full-Bridge Converter Power Supply Based on UCC3895

Abstract

A high efficiency full-bridge converter is designed and implemented in this paper. The measured data result from the other converter implemented by IC UCC3895 compares with that of the previous converter. This full-bridge converter of phase shift soft switching can obtain about 92% power efficiency in conversion procedure. This design used L-C resonance circuits to achieve power switch tube soft switching.
