| 摘 要： | 与基于载波的正弦脉宽调制(SPWM)相比,空间矢量脉宽调制(SVPWM)因其较高的电流(电压)利用率,在电压源变换器(VSC)中获得了广泛应用,而在电流源变换器(CSC)中,SVPWM技术较难实现。为了在CSC中使SVPWM技术的实现更加容易,提出了一种间接PWM调制方法,该方法通过将双逻辑信号转换为三逻辑电平信号,从三相VSC的调制策略中得到三相CSC的调制策略,提出了一种七段调制方法。通过仿真结果验证表明,间接PWM调制方法具有易于实现、交流侧电流谐波小、直流侧电流脉动小等优点。

| Abstract: | Compared with sinusoidal pulse width modulation(SPWM)based on carrier,space vector pulse width modulation(SVPWM)is widely used in voltage source converters(VSC)for its high curren(t voltage)utilization.In current source converters(CSC),SVPWM is difficult to realize.In order to make the realization of SVPWM technology easier in CSC,an indirect PWM modulation method was proposed.This method could obtain the modulation strategy of three-phase CSC from the modulation strategy of three-phase VSC by converting the double-logic signal into the three-logic level signal,and a seven-phase modulation method was proposed.Finally,the simulation results show that the indirect PWM modulation method has the advantages of easy implementation,low harmonic current at the AC side and low current ripple at the DC side,etc. |
