چکیده

DriviNG eGaN® FETs When considering gate drive requirements, the three most important parameters for eGaN FETs are (1) the maximum allowable gate voltage, (2) the gate threshold voltage, and (3) the “body diode” voltage drop. The maximum allowable gate-source voltage for an eGaN FET of 6 V is low in comparison with traditional silicon. Secondly, the gate threshold is also low compared to most power MOSFETs, but does not suffer from as strong a negative temperature coefficient as MOSFETs. Thirdly, the “body diode” forward drop can be higher than comparable silicon MOSFETs, which requires additional attention to timing for the gate drive as compared to MOSFETs.

Monolithic Integration of GaN Transistors for Higher Efficiency and Power Density in DC-DC Converters

Power converters are constantly trending towards higher output power, higher efficiency, and higher power density. To provide improved performance better power devices are required. For silicon (Si) power devices, the gains in performance have slowed as the technology has matured and approaches its theoretical limits [1]. Gallium nitride (GaN) devices have emerged as a possible replacement for ...

Performance Comparison for A4WP Class-3 Wireless Power Compliance between eGaN FET and MOSFET in a ZVS Class D Amplifier

eGaN FETs have repeatedly demonstrated higher efficiency than MOSFETs in wireless power transfer amplifiers when operated over a wide impedance range using a ZVS Class D amplifier [1, 2, 3, 4, 5, 6, 7, and 8]. In this article we examine a method to further improve the performance of eGaN FETs by replacing the bootstrap diode of the high side gate driver with an eGaN FET that is driven synchrono...
