摘要：
This paper proposed a resonant switched capacitor converter (RSCC) using hybrid SiC IGBT (HSiC-IGBT) and all SiC-MOSFET power modules, respectively. RSCC adopts modular structure to reduce the voltage stress of switching devices, and uses resonance mechanism to realize soft switching transition, which can effectively suppress current and voltage spikes. Then the phase shift control was used to improve output performance. Followed by the analysis of the configuration and operation principles, detailed study of the mathematical model and output characteristics of the proposed converter were carried out. Then the effect of HSiC-IGBT and SiC-MOSFET device parameters on the proposed converter were compared. Moreover, the feasibility of the proposed RSCC and the control strategy were also verified. Experimental results show that, the phase shift control effectively improves the unbalance of DC capacitor voltages. © 2020 Chin. Soc. for Elec. Eng.
