GaN is a game changer for motor drive applications. For designers to take advantage of this technology, fast and reliable time-to-market is critical. Easy-to-use reference designs using state-of-the-art electronics and techniques provide a valuable tool to speed time to market. The EPC9173 tool allows designers of eBikes and drones to enhance motor system size, performance, range, precision, and torque, all while simplifying design for faster time-to-market.
The EPC9173 integrates all the necessary circuits to operate a 3-phase BLDC motor with high performance, 48 V input, 1.5kW output, and three-phase inverter using six EPC23101 GaN ICs. Thanks to the high-power density and the high electrical conductivity of GaN ICs, the EPC9173 delivers up to 25 ARMS on each leg and supports PWM switching frequencies up to 250 kHz under a natural convection passive heatsink. The resultant quality of the current output waveforms, lesser torque oscillations, and total system efficiency increase the performance of the motor-drive system. Further, the extremely small size of this inverter allows integration into the motor housing resulting in the lowest EMI, highest density, and lowest weight.
