阴调脉冲发射机中高压电源的抗干扰设计

Design of ECCM of high-voltage power supply in cathode-modulated pulse transmitters

阴极调制方式发射机直接控制发射管的阴极,是一种特大功率的调制方式,在调制器开通关断瞬间可释放大量电磁辐射,将干扰其他分机的正常工作。而作为发射机工作的能量源,高压电源与调制器、发射管处于同一个高压回路中,因此受到的电磁干扰也最为严重。本文以某型雷达为例,着重讨论在阴极调制方式发射机中高压电源的抗干扰设计。

The cathode modulation mode in which the transmitter directly controls the cathodes of the transmitting tubes is a super high-power modulation mode. A large amount of electromagnetic radiation is released when the modulators are on and off, which affects other units＇ normal operation. The high-voltage power supply as the energy sources of the transmitter is in the same high-voltage loop with the modulators and the transmitting tubes. Therefore, it suffers the most serious electromagnetic jamming. The ECCM of the high-voltage power supply in the cathode-modulated transmitter of certain radar is designed and discussed.
