Actual Motor Controller Based on SiC Power Module

Compared with Si devices, SiC devices have lower energy loss, better temperature characteristics, and higher operating frequencies. They have great advantages in high voltage, high power, high temperature, and high frequency applications, which can effectively improve system efficiency and reduce Energy consumption, reducing the size and weight of the device, thereby improving system reliability, is one of the main development directions of power electronic devices. The performance of traditional Si devices and SiC devices were compared and analyzed in this paper, and the advantages of SiC devices were summarized. Furthermore, the performance parameters of SiC MOSFET used in motor controller were analyzed, and the parameters were compared with IGBT based on traditional silicon materials. According to the current research progress of SiC devices, the circuit schematic design of the motor controller based on SiC power module was carried out. Through the above steps, a design scheme of motor controller based on SiC power module was given¹.
