具有可控相位和幅值的单级交流-交流变换器

Single-stage ac-ac converter with controllable phase and amplitude (ACCPA) was proposed for power flow control in grid, whose output voltage phase and amplitude can be regulated, respectively and simultaneously, with respect to the input voltage. Single-stage ACCPA comprises of a three-phase input transformer, three single-phase buck-type ac units, a three-phase output filter, and a three-phase ou...
