| Outline of Final Research Achievements |
This research focuses on a three-phase inverter using a Si-MOSFETs and SiC-SBD to realize a higher-frequency switching operation and discusses both the loss analysis and thermal resistance. First of all, a laboratory experimental system of a PWM inverter focused on a cooling structure is produced with separating heat sinks. The experimental results for 300-kHz switching operation rated at 300 V and 3.2 kVA are presented to verify the separating heat sinks structure. Secondly, this research discusses a gate drive circuit without the dead time for high-frequency switching PWM inverter. In order to realize the dead-time less inverter, the 5-V gate drive circuit is proposed. The experimental results, rated at 500 kHz switching frequency and 300 V DC, are presented.
