GaN-Based Low-Voltage Inverter for Electric Scooter Drive System

GaN-Based Low-Voltage Inverter for Electric Scooter Drive System

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.

GaN ICs Shrink Motor Drives and Speed Time-to-Market for eMobility, Power Tools, Robotics, and Drones

GaN ICs Shrink Motor Drives and Speed Time-to-Market for eMobility, Power Tools, Robotics, and Drones

The EPC9176 GaN-based inverter reference design enhances motor drive system performance, range, precision, torque, all while simplifying design. The extremely small size of this inverter allows integration into the motor housing resulting in the lowest EMI, highest density, and lowest weight.

EL SEGUNDO, Calif.— October, 2022 — EPC announces the availability of the EPC9176, a 3-phase BLDC motor drive inverter using the EPC23102 ePower™ Stage GaN IC with embedded gate driver function and two GaN FETs with 5.2 mΩ typical RDS(on). The EPC9176 operates from an input supply voltage between 20 V and 80 V and can deliver up to 28 Apk (20 ARMS). This voltage range and power level makes the solution ideal for a variety of 3-Phase BLDC motor drive applications with 36 V – 80 V input including eBikes, eScooters, power tools, drones, robots, DC servo, medical robots and factory automation.
