Design of Gyrotron Filament Power Supply for Magnetic Confinement Fusion Electron Cyclotron System

釆用零电压开关(ZVS)移相全桥拓扑结构设计了一款带输出电压反馈的大功率回旋管灯丝电源。本文详细地叙述了本次设计电源的整体架构、重要参数的计算过程、输出电压控制电路及其优点。最后实测了样机的主要波形与关键参数,并通过老化试验验证了其稳定性。

The Phase-shifted Full-bridge Zero-Voltage Switching topology was used to design a high- power gyrotron filament power supply with output voltage feedback. This paper introduced the architecture of the power supply, calculation process of key parameters, output voltage control circuit and the advantages of the output voltage control circuit. At the end of this paper, the main waveforms and key parameters of the prototype were measured, and the stability was verified by the aging test.
