摘要:
高压直流电源是ECRH (Electron Cyclotron Resonance Heating)系统最重要的组成部分之一，其工作的稳定性与可靠性直接影响整个系统的运行。本文介绍了一种ECRH高压直流电源的研制方案，用PSM (Pulse Step Modulate)模块电源技术，克服了传统高压电源单机体积大、效率低、网侧低次谐波污染、功率因数低、输出纹波大、动态响应慢等缺点，同时具备1 kHz的调制能力。并通过Simplorer软件仿真和实验，验证了该设计方案的正确性。
High voltage DC power supply is one of the most important parts of ECRH (Electron Cyclotron Resonance Heating) system, and its stability and reliability directly affect the operation of the whole system. The article introduces a design method of ECRH, using PSM (Pulse Step Modulate) module power supply technology, which overcomes the shortcomings of the traditional high voltage power supply, such as large single volume, low efficiency, net side low harmonics pollution, lower power factor, larger output ripple, slower dynamic response and so on. Meanwhile, it has the capacity of 1 KHZ modulation. Furthermore, the simulations of the Simplorer Software and the results of experiment are provided to verify the accuracy of the proposed design method.
