Research on Soft Switching Inverter for Permanent Magnet Synchronous Motor Based on Simscape

PMSM inverters are developing towards high frequency and high voltage levels, and the power loss and electromagnetic interference EMI of inverters have become increasingly serious. The use of ARP soft switching technology can effectively optimize power loss and EMI characteristics of inverters. The paper conducts research from multiple aspects such as topology design, modulation methods, and parameter selection, and the results show that the power loss of the inverter is significantly reduced, and the EMI is also optimized.
