How to Design a Vacuum Cleaner Motor Drive Inverter Using EPC9176 Evaluation Boards
■The EPC9176 is a 48 V input, 400 W output, equipped with the EPC23102 eGaN ICs, designed for vacuum cleaner applications. It integrates all the necessary circuits to operate a 3-phase BLDC motor with high performance. Thanks to the high power density and the high electrical conductivity of eGaN, the board delivers up to 18 ARMS on each leg and supports PWM switching frequencies up to 250 kHz under natural convection passive heatsink and by keeping the temperature rise below 50°C. Increasing performance of the motor-drive system in terms of quality of the current output waveforms, lesser torque oscillations, and total system efficiency are achieved.
