摘　　要：现代电力试验电源越来越朝小型化、高频化、模块化方向发展,DC/DC模块作为电力试验电源的核心部分,其设计合理与否影响电源的整体性能。本文采用ZVS移相全桥为主电路拓扑,分析了一种数字控制的设计方案,有良好的应用前景。设计并调试了一台2.2k W,输出电压25－220V可调的实验样机。样机输出稳定、效率高,验证了设计方案的可行性。Nowadays, the test power supply is gradually developing toward the direction of miniaturization, high frequency and modularization. Its design is reasonable or not plays an important role in the monolithic performance of the power. The article analyzes the design scheme of a digital phase-shifted control, taking advantage of the phase-shifted full bridge （PSFB） topology. The design scheme will have favorable application foreground. The 2.2kW experimental prototype which has stable output and high efficiency is built and verifies the design scheme.
