According to the principle of DC injection, the topology of a 12-pulse current source converter based on autotransformer is proposed. The Main bridge topology is a autotransformer, and each injection branch consists of a double winding reactor and a IGBT and a diode in series. DC injection could make the main bridge realize zero current switching and operate in four quadrants. The system control method is presented on 9-level topology. The simulation based on MATLAB shows that the topology has… CONTINUE READING
