摘　　要：双行波管放大器因其体积、重量的显著优势,在通信卫星转发器分系统中广泛应用。本文设计了一种星载双行波管放大器电源,通过优化设计倍压整流电路和增加次级谐振网络,降低了多路输出应用场合下漏感对电压稳定度的影响,使多路高压输出电压在宽负载范围变化时具有良好的交叉调整率,大幅提高了放大器整机的效率和可靠性。Dual-TWT amplifiers are widely used in communication satellite transponder subsystems because of the significant advantages in volume and weight.A power supply for dual-TWT amplifiers is designed.With the optimization of voltage-doubling rectifier circuit and the employing of secondary resonant network,the influence of leakage inductance on voltage stability in multiple output applications is reduced,so that the multiple high-voltage outputs have low cross-regulation when changing in a wide load range,and the efficiency and reliability of the amplifier are improved greatly.
