摘要 国产高压变频器主电路型式包括二电平高进高出无需变压器的型式、三电平需要输入三绕组变压器的型式及多电平需要输入移相多绕组变压器的型式三种。具体介绍了国产单元串联多电平中高压变频器的控制型式、优越特性和不足之处,指出了以多相整流输入,三电平输出改进的必要性和具体方法,同时分析了其改进后的性能。 Types of domestic high-voltage inverter main circuit including two level into the higher level without the transformer type,three-level need to enter the three-winding transformer type and multi-level need to enter phase three types of multi-winding transformer.The production of domestic unit series multi-level mid-voltage inverter,the control type's advantages and the shortcomings of mid-voltage inverter were introduced,improved necessity and specific methods of multi-phase rectifier input and three-level output were pointed out,and the performance was analyzed.
