Design of Phase-Shifted Full-Bridge Switching Power Supply Transformer

摘要

The design of the switching power supply transformer, applied to the phase-shifted full-bridge inverter circuit as an example, is discussed in this paper. First, the main circuit of the phase-shifted full-bridge inverter is presented, and the basic design considerations from references are reviewed. Then the design processes are presented step by step, in which the detailed calculations are provided. Finally the testing data of some samples is given, and some suggestions are offered to get best efficiency and performance, which is helpful for practical design and production.
