This paper deals with the application of the latest generation low voltage (up to 80 V) Gallium Nitride (GaN) devices for motor drive applications in the field of electric micro-mobility. A two-level inverter topology oriented to light electric traction (such as electric scooters) with a power rate of 1500 W has been considered. An experimental board using two GaN FETs in parallel connection for each switch of an inverter leg has been arranged. The intrinsic parameters spread of the device, as well as the leakage inductances of both the circuit and the PCB, to evaluate the impact on the current share during both the transient phase and in the steady state have been investigated. In the paper, several simulation runs have been carried out and described. Furthermore, the inverter experimental board has been used to evaluate the phase voltages and currents at different load conditions. Finally, the temperature limits versus phase current variation have been evaluated.

Join host Dr. Sanjay Gupta and guest Alex Lidow, CEO of Efficient Power Conversion – or EPC – in episode 5 as they explore the ways GaN is advancing the future of wireless charging. As wireless power increases in maturity and adoption, the industry needs solutions that improve performance, efficiency, and user experience. Gallium Nitride is essential to enabling higher power applications than can be achieved with traditional silicon, opening the door for charging multiple devices and more diverse devices, such as laptops, drones, robots, power tools, eBikes, and industrial equipment. Wireless charging circuits employing GaN transistors are also five to ten times smaller than silicon devices able to handle the same power levels.
