| 摘 要： | 单相PWM整流器作为串联H桥多电平变频器的有源前端,可以满足矿井提升机对电气传动系统能量双向流动能力的要求,但是其输出2次脉动电压使得网侧电流存在3次谐波。针对上述问题,提出了一种稳态误差前馈补偿的方法,即将输出直流电压的二倍频正弦误差信号补偿至直流电压给定信号,以减小电压脉动对电网电流畸变的影响。仿真及硬件实验验证了该方法的有效性。

| Abstract: | To take single-phase PWM rectifier as AFE of cascaded H-bridge multi-level frequency converter can satisfy requirement that electric drive system of coal mine hoist must have capacity of bidirectional energy flowing,but there are third harmonic in its AC-side current because of the second ripple of output voltage.To slove the problem,a method of steady-state error feed-forward compensation was put forward,namely frequency-doubled sinusoidal error signal of output DC voltage is compensated to set signal of D... |
