摘　　要：本文研制了以DSP为控制核心,集中实现了移相全桥逆变技术、电源输出调压和过压过流保护等功能的新型直流高压发生器。该新型直流高压发生器使用高频开关技术和集成驱动芯片,使装置的体积小,调压响应平稳、快速;输出电压稳定度高,纹波系数小,电路抗干扰能力强;实际应用达到了预期的设计效果。DSP core has been developed in this paper. The phase-shifting full-bridge inverter technology, voltage regulating and protection of over voltage and over current applied in new type high DC voltage generator, high-frequency switching technology and integration driver chips applied , smaller size of the device ,more steady and rapid surge response, more stability of output voltage, smaller ripple coefficient, circuit capability of anti-disturbance can be got .As a result ,good expected effect was achieved.
