| Abstract: | New generation of wide band-gap power semiconductors which use silicon carbide (SiC) material have excellent performance of high blocking voltage, low on resistance, low switching loss, and high temperature resistance, and so they have good application potential in motor drive system. This paper applies SiC MOSFET to the high-speed permanent magnet synchronous motor system in fuel pump to reduce the heat dissipation volume and improve the power density. To improve the dynamic response of the current control, the current loop is improved by optimizing the current sampling time, and the experimental results show that the system can achieve good performance and widen the current loop bandwidth. |
