摘要
A multi-branch current sensing technique for three-phase current reconstruction with a non-contact-type current sensor is introduced. In the proposed method, the non-contact-type current sensor measures two branches%26apos; current simultaneously in a three-phase inverter, and all phases%26apos; current information is obtained in a single switching cycle. The proposed method completely takes the advantages of the previous multi-branch current sensing technique, and even further accuracy improvement is achieved. The proposed method is verified through experiments.
