This paper proposes a hybrid-switch three-phase current source rectifi er (CSR) solution, which employs only one silicon carbide (SiC) switch and six traditional silicon (Si) switches. The corresponding hierarchical discontinuous pulse widthmodulation (HDPWM) strategy for the proposed CSR is also presented, which uses two parallel carrier-based discontinuous PWM branches to perform diff erentiated modulation operations on Si and SiC devices to endow the Si switches with zero current switching capability and conveniently make full use of the high-speed and low-loss advantages of SiC devices. Consequently, the proposed hybrid-switch CSR with HDPWM can even work as a full SiC device-switching converter with relatively lower costs, thus addressing the critical needs of effi ciency promotion of CSR applications. MATLAB simulations and experimental verifi cations were conducted to verify the performance of the proposed CSR solution.
