摘要:
六开关三相四线PWM整流器拓扑是适合于中大功率高频UPS装置的前级整流器拓扑。与常规的六开关三相三线整流器相比,三相四线整流器输出正负直流母线,并且输入侧存在零序电流通路,如果沿用三相三线整流器的控制方法,必然会引起很大的中线电流。针对此问题。讨论了三相四线PWM整流器输出为正负直流母线电压均衡控制和中线电流控制问题,建立了三相四线整流器数学模型,分析了中线电流产生的机理以及抑制的方法,设计了基于同步旋转坐标系的三相四线整流器的控制算法。在功率40kW的实验样机上验证了控制方法的有效性,保证了输出正负母线电压的平衡及较小的输入电流谐波。
Abstract:
The six switches three-phase four-wire rectifier is an appropriate front stage rectifier of the higher power high frequency UPS.Compared with the three-phase three-wire rectifier,the four-wire rectifier produces the positive and negative DC link voltage.For the existence of the zero-wire,the central current would be serious if the control method of three-wire rectifier is used to control the four-wire rectifier.Both the balance control of positive and negative DC link voltage and the probiem of central wire current control are discussed.The mathematic model of three-phase four-wire rectifier is built.The original and control method of the central wire current is analyzed.The control system based on synchronous coordinate is built.A 40kW prototype with wonderful experimental results was built to verify the effectiveness of the controlled strategy.
