A type of continuous switched boost inverter was used to improve the control performance of permanent magnet synchronous motor (PMSM) through predictive control, aiming at the drawback of the traditional PMSM drive system. By adding a switched boost circuit between the inverted circuit and input DC power, switched boost inverter circuit was formed to achieve higher voltage gain and eliminate the dead zone. Meanwhile, the drive system had higher reliability. Moreover, predictive current control (PCC) was adopted to control PMSM. In comparison with the traditional field oriented control, PCC had faster dynamic response and could reduce current ripple. Finally, experiment results verified the feasibility of the predictive current control for PMSM based on the continuous switched boost inverter.
