【Abstract】 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.更多还原
