Abstract

BLDC IPM motor drive PMSM SiC MOSFET Energy Engineering and Power Technology Electrical and Electronic Engineering Safety Risk Reliability and Quality Electronic Optical and Magnetic Materials Radiation
SiC MOSFETs are a beneficial solution in motor inverter applications because of their remarkable intrinsic diode reverse recovery behavior. SiC MOSFETs have successfully emerged as the best choice as devices for realizing high performance and high power motor drive in, for example, electric vehicles, but have rarely been used in low power motor drive for applications. In this work, an all-in-one system integrated SiC intelligent power module, which integrates the MCU, memory, SRAM, motor control library, ADC, DAC, gate drivers, and SiC MOSFETs was proposed to explore the benefits and potential of SiC MOSFETs in highly integrated BLDC/PMSM motor drive. As a result, SiC solution generally saves over 80% of space, improves the thermal performance by 27.7°C, and enhances 3% of efficiency compared to the silicon counterparts.
