| Popis: | Fast switching operation of power electronics systems is significantly advantageous for reducing volume of passive components and increasing power density in the systems. Next generation power devices, such as GaN gate-injection transistor (GIT), are promising for high frequency operations and isolated gate driving is also highly recommended owing to its noise robustness. In this paper, we propose a GaN Hetero Junction Field-Effect Transistor (HFET)-based isolated gate driver for GaN power devices with Drive-by-Microwave (DBM) technology, which can provide very compact GaN-GIT power systems owing to a gate driving by a wireless power transfer without an additional isolated voltage source. The proposed DBM gate driver can drive GaN-GIT power devices at a high switching frequency of 3 MHz with relatively low power consumption (∼1 W) and provides a short propagation delay less than 20 nsec. |
