SPEED CONTROL OF PERMANENT MAGNET SYNCHRONOUS MOTOR USING FPGA FOR HIGH FREQUENCY SIC MOSFET INVERTER

This paper proposes a digital hardware control of Permanent Magnet Synchronous Motor (PMSM) using a SiC MOSFET inverter implemented in a FPGA (Field Programmable Gate Array) device. High frequency is required using a SiC MOSFET inverter to obtain high response and good stability for speed control systems. Not only the switching frequency of inverter, but also the control frequency is achieved up to 100 kHz for speed control system of AC motor drive including vector control and dq transformation. As the result, high response control system of PMSM can be achieved. Digital hardware control based on FPGA is used to maximize the switching frequency of SiC MOSFET inverter. Finally, an experimental system is set up and some experimental results are demonstrated.
