Abstract
The central focus of this research is to enhance the efficiency of a traction hybrid switch inverter designed to operate at a DC-link voltage of 400V. This enhancement is accomplished through the integration of discrete 650V Si- IGBTs and freewheeling diodes in conjunction with 650V SiCMOSFETs, forming a parallel configuration. The study describes an innovative approach involving the introduction of an additional inductance to decouple the SiC-MOSFET half-bridge from the IGBT/Si-Diode half bridge. This decoupling methodology effectively mitigates the turn-on losses of the active SiC-MOSFET and the turn-off losses of the passive Si-diode, resulting in a notable reduction in overall losses within the hybrid-switch inverter compared to a non-decoupled configuration. The comprehensive assessment of the system losses within the hybrid-switch inverter is conducted through simulations and subsequently validated via experimental setups. These experimental setups encompass a double pulse test configuration and an H-bridge inverter test setup, ensuring the accuracy and reliability of the research findings. After experimental validation of the simulation model the average losses of a driving cycle are calculated, to find the best decoupling inductance value.
