摘要三相电压型PWM整流器可以减小输入电流谐波含量,提高系统功率因数,因而广泛应用于人们的生产生活中。在传统的三相三桥臂整流器拓扑基础上,引入第四桥臂可构成三相四桥臂整流器拓扑。作为3P4W系统拓扑中的一种,三相四桥臂整流电路的提出丰富了三相电压型PWM整流器的拓扑结构,如果选用合适的控制方法,相比较传统的三相三桥臂PWM整流器,三相四桥臂整流电路可具有更优良的工作性能。本文首先通过开关平均周期法对三相四桥臂整流电路建立开关平均模型,指出了三相四桥臂整流器可以分解成三个相互解耦的单相整流电路。分析了三相四桥臂整流器在SPWM控制策略下的不足,研究了系统SAPWM控制策略及其实现方法。基于SAPWM控制策略下的三相四桥臂整流器降低了输出直流电压,提高了直流母线电压利用率,进而降低元器件耐压等级。最后通过系统仿真与实验验证了理论分析的正确性。

Abstract：The three-phase voltage mode PWM rectifier is widely used in the production for reducing the input current harmonic content and improving the power factor of system. On the base of traditional three-phase three leg rectifier, the three-phase four legs rectifier is obtained by introducing a forth leg. As one of the 3P4W topologies, the proposed three-phase four legs rectifier riches the topology of three-phase voltage mode PWM rectifier. If the appropriate control method could be chose for three-phase four legs rectifier, and the rectifier would have a more excellent work performance than the traditional three-phase three legs rectifier. The switch average period model of three-phase four legs rectifier is given in the paper by the way of average switch period, and the three-phase four legs rectifier can be decoupled to three single phase rectifiers. The shortage of SPWM(sinusoidal pulse width modulation) control strategy for three-phase four legs rectifier has been analyzed. The SAPWM (saddle pulse width modulation) control strategy is proposed to obtain a lower output voltage and improve the DC voltage utilization rate. Finally, simulation and experimental results of the system verified the theoretical analysis.

Key words： Three-phase four legs rectifier SAPWM control strategy
