摘　　要：描述了一种适用于脉冲行波管雷达发射机的高压电源设计方案。分析移相控制方式串联谐振变换器的工作原理。该变换器在传统的串联谐振变换桥中,增加了4只二极管对回路中谐振电容电压加以箝位,使电路具有良好的脉冲负载适应特性,同时功率开关器件具有较宽的软开关范围,在高频工作状态下,仍然具有高的变换效率。最后给出该电源的实际工作波形。The design of high-voltage-power for pulse-Travelling Wave Tube （TWT） radar transmitter is presented.The operation principle of the series-resonant converter operating at phase-shifted is analyzed.This converter was created from a conventional series-resonant converter by adding four diodes to clamp the resonant capacitor.The converter output characteristics for pulse-load were improved, and the switches turn-on or turn-off with zero-current/zero-vohage were easily. In this way a high efficient was achieved.Finally, the operation waveforms of the high-voltage-power are given.
