| 摘 要： | ECRH阳极高压电源系统由高压直流电源及调制器两部分组成。高压直流电源采用晶闸管调节升压变压器的输入电压，在低电位端利用三极管串联线性调整输出DC电压，控制器采用了内外双闭环控制技术，其最大输出为30kV/130mA；调制器使用真空四极管为核心部件。使用仿真软件对电路进行了优化设计。独立调试实验及HL-2A装置放电实验数据表明，该电源系统具有大范围调压、低纹波输出、快速调制等特点。

| Abstract: | The anode high voltage power supply system consist of DC high-voltage power supply (HVPS) and pulse modulator. SCR is used to vary AC input voltage of the step-up transformer by controlling the trigger phase in the HVPS, and regulate the DC output voltage linearly at the potential of low-end via BJT, Dual closed-loop control technology is applied in the controller, and its maximum output is at 30kV and 130mA. Tetrode is the core component of the modulator. The circuit design is optimized by using the simula... |
