Abstract :
This paper presents a topology of cascaded multiple level PWM AC/DC converter with VIENNA cell for the application in High Voltage Direct Current Transmission (HVDC). Through a proper control method the proposed converter can be operated with unity power factor and the output voltage is increased. A detailed process of building mathematical model of the circuit is given. At last, according to the simulation results of the cascaded converter with three VIENNA cells, the correction of the new topology is validation.
