摘要
电力试验电源是电力工业中的重要设备，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着电源的整体性能．移相全桥变换器具有软开关、效率高等优点，广泛应用于大功率场合．本文以ZVS移相全桥为主电路拓扑，分析了一种数字控制电力试验电源的变匝数渊压方案，具有良好的应用前景。设计并调试了一台2．2kW，输出电压25～220V可调的实验样机、样机输出稳定、效率高，充分难设计方案的可行性。
Test power supply acts as an important role in electric power industry. The DC/DC modular is the core part of test power supply. It effects the overall performance of test power supply whether the DC/DC modular is reasonably designed. Phase Shifted Full Bridge converter is widely used in high power applications because of its soft switching and high efficiency. The article analyzes the design scheme of a digital controlled changing turns test power supply, 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
