Abstract:
A new Drive-by-Microwave (DBM) isolated gate driver with gate current charge is presented, which drives an IGBT without an isolated power supply by switching the charged current through a microwave wireless power transmission. The fabricated compact DBM gate driver outputs an isolated gate voltage of 15V and successfully demonstrated the 300A-IGBT drive with the 2.0A peak gate current. Furthermore, the fabricated DBM gate driver realizes a 100V and 5.0MHz high-speed switching of a GaN power device without photo couplers and bulky transformers.
