It is the main development tendency that high frequency, modular construction and digitalization are adopted in the field of the switching power supply. To realize high power density and high frequency conversion,it has need of soft-switching techniques. Full bridge phase-shifted zero-voltage-switched converter (FBPS-ZVS Converter) is the better equipment used in DC/DC converter. The core technique to reach digitalization is DSP technique. In order to reach both high frequency and digitalization of converter, a FBPS-ZVS Converter based on DSP control is proposed in this paper.%高频化、模块化、数字化是开关电源的发展方向.实现高频化的主要途径是软开关技术,全桥移相零电压脉宽调制变换器是软开关PWM技术在全桥直-直变换器中较成功的应用例子,并具有较好的工程实现价值.实现数字化的核心是DSP技术.将开关电源的高频化与数字化相结合,具体研究内容为一种基于DSP控制的移相全桥软开关ZVS变换器.
