- An improved pulse amplitude modulation (PAM) control method based on fuzzy logic with automatic excitation angles (120-180 deg) was successfully developed and implemented in the experimental IPMSM drive system excited by a silicon carbide (SiC)-MOSFET inverter. In addition, a novel auto-tuning proportional derivative (PD) control scheme based on fuzzy logic for the IPMSM current harmonics to lower the motor copper loss and SiC inverter loss was proposed and evaluated in experiments.- The impacts of dissimilar dead-times and control sample times of the SiC-MOSFET inverter on the IPMSM core loss and inverter loss with the pulse width modulation (PWM) technique at high carrier frequencies of up to 200 kHz were experimentally performed. The effects of the gallium nitride (GaN)-FET inverter and output LC filter on the IPMSM losses and inverter temperature with the PWM technique at high carrier frequencies of up to 400 kHz were conducted in experiments.- Furthermore, the IPMSM control system in MATLAB/Simulink and its finite element analysis (FEA) models in JMAG to assess the core loss of the IPMSM excited by the inverter were developed. The analysis results were compared to the experimental findings. Besides, the extended building factor to thoroughly analyze and evaluate the increase in the IPMSM core loss under the sinusoidal and inverter excitations was designed.- The achieved research results in FY2022 were published in IEEJ Journal of Industry Applications, international conferences (IPEC-Himeji 2022, IEEE ICCE 2022, SICE ISCS 2023), and domestic conference IEEJ IAS 2022.
