要約(英語): GaN power devices improve the performance in power conversion circuits. Since the current rating of the GaN devices is still small, many devices must be connected in parallel to create a large-current power module. Device cooling and low stray inductance are the major challenges in designing a high-power half-bridge circuit with multi-parallel GaN devices. In order to overcome these challenges, we propose an inverter circuit structure with 12 parallel GaN devices capable of double-sided cooling and a well-balanced stray inductance. Such a system is applicable to electric vehicle design.
