Analysis the reverse conduction characteristic and influence of anti-parallel SiC SBD of eGaN HEMT
Paper in proceeding, 2019

eGaN HEMT has been developed with up to 650V blocking capability with lower conduction losses and higher switching speed compared MOSFET. Self-commutated reverse conduction is a very important characteristic of eGaN HEMT, especially for synchronous rectification topologies. This paper introduces the reverse conduction mechanism and characteristics of eGaN HEMT, and establishes a double pulse test platform to explore the influence of anti-parallel SiC SBD for eGaN HEMT on the reverse conduction characteristic and switching characteristic of eGaN HEMT, which will provide some help for the application of the eGaN HEMT's self-commutated reverse conduction.
