Abstract

In view of problems that utilization coefficient of DC bus voltage is not high in traditional driver of PMSM which uses sine pulse width modulation technology, the paper proposed a design scheme of control system of PMSM based on SVPWM. It analyzed working principle of the system and expounded implementation of SVPWM algorithm, and gave design of hardware and software of the system. The experiment result showed that the system has quick starting speed and reliable running.
