用于船舶推进直驱多相永磁同步电机的混合SiC-Si牵引逆变器控制策略

This article introduces a novel inverter structure tailored for direct-drive marine propulsion applications, integrating SiC-MOS and Si-IGBT devices in a hybrid bridge arm configuration. The scheme aims to enhance torque control performance by raising the switching frequency of the SiC-MOS and to minimize losses in the propulsion system by lowering the switching frequency of the Si-IGBT. Methods f...
