摘　　要：阳极控制行波管在宽带、连续波发射机中应用普遍,阳极电压的产生有多种方式,通常采用的阴极电压电阻分压方式简单易行,但电流适应能力差.随着开关电源技术的进步,小功率的独立阳极电源方案成为一种选择.通过比较几种阳极电压实现方案,分析了各自的优缺点,提出了一种适应能力强的阳极电源方案.A traveling-wave tube （TWT） with anode control is widely used in wide-band CW transmitter.There are several modes to generate the required anode voltage, where the cathode voltage’s resistor dividercommonly used is easy and practicable while its adaptability of current is poor. With the progress of switchingpower supply technology, the individual anode power supply with low power is a reasonable choice. This papermakes comparisons among several implementation schemes of anode voltage, analyzes the merit and demerit ofeach scheme, and finally presents an implementation of anode power supply with a robust adaptability.
