The practical realization of a novel concept for output voltage control and mains voltage proportional guidance of the input currents of a three-phase/switch/level PWM (VIENNA) rectifier system being connected to a heavily unbalanced mains is presented. The control is investigated experimentally for a wide input voltage range 6.5 kW prototype of the VIENNA rectifier.read more
