Power-conversion technologies are experiencing the first tectonic shift since the move from bipolar to MOS. That shift, of course, is due to the viral adoption of wide-bandgap power devices. At this point, GaN is more than a specialty technology; it is a broad-scale replacement for silicon MOSFETs in applications ranging from 30 V up to 650 V — a multibillion-dollar market.

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.

There is a commonly held belief in the industry that GaN devices are wasted on inverters for electric motors. After all, if the performance of the system is restricted by the use of a 20KHz PWM, then there can be little benefit in using a material that gains the majority of its advantages from faster switching speeds. However, according to Marco Palma, Director of Motor Drives Systems and Applications at EPC, there are some ways that GaN can still prove effective in that role.
