摘要
针对相控阵雷达电源系统中380V三相交流电源对功率因数校正(PFC)极高的改善需求,深入研究了Vienna拓扑的工作原理及关键电路的设计。设计出电流内环、电压外环的双闭环PWM控制算法,并添加了输出电压平衡控制器,在数字信号处理(DSP)控制器上实现了数字化控制。在三相三线制380V交流输入条件下,所研制的三相有源PFC电源模块功率能够达到5.5kW,额定条件下各相谐波电流小于3%,功率因数(PF)值接近于1,功率因数校正效果优异,极大地提高了相控阵雷达电源系统的电磁兼容水平。
In view of the extremely high demand to the improvement of power factor correction(PFC)in 380 V3-phase AC power supply of phased-array radar,this article deeply studies the operating principle of Vienna topology and the design of key circuits,designs the double closed loop pulse width modulation(PWM)control algorithm with inner current loop and outer voltage loop,adds the output voltage balance controller,and realizes digital control in digital signal processing(DSP)controller.With the input of 380 V3-phase 3-wire AC,the power of active 3-phase PFC module developed can reach 5.5 kW;the harmonic current under rated condition is less than 3%,and power factor value is close to 1;the PFC effect is excellent,which greatly improve the electromagnetic compatibility level of phased-array radar.
