| Abstract |
A new isolated gate driver with Drive-by-Microwave (DBM) technology 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 15V voltage and successfully demonstrated the IGBT drive with a 100 kHz. Furthermore, the fabricated DBM gate driver realized a 100V and 5.0MHz switching of a GaN power device without photo couplers and bulky transformers. |
