| Abstract: | This paper introduces a new type of voltage regulating method with star-point controller of the high voltage phase control rectifier. The booster transformer with such circuit structure can transform modulation from high voltage to low voltage, and thus make it very convenient to deal with the problems such as voltage withstand of thyristor, insulation and control of reactor, etc. The filter inductance on HVDC bus can also be equivalent to low voltage side, so that to decrease the inductance scale significantly. |
