本文分析了的120°导通三相逆变器的SVPWM控制特性,提出了基于SVPWM控制和电流调节控制的无位置传感器的三相永磁无刷直流电机（BLDCM）的起动控制方法。在Matlab/Simlink环境下,建立了三相永磁BLDCM起动控制系统的仿真模型并进行了仿真。仿真结果表明该起动控制方法不但能有效控制起动电流大小,而且能改善BLDCM开环起动性能。

The paper analyses the SVPWM control schema of three-phase inverter employing 120° switch-on mode,proposes a starting control method combining the SVPWM control schema with current regulation for a sensorless three-phase permanent-magnet（PM） brushless DC（BLDC） motor,establishes the simulation model of the starting control system in Matlab /Simlink environment,and implements the proposed starting control system through digital simulation.Simulation results verify that the proposed starting method can not only control the starting current effectively but also improve the open-loop starting performance of the BLDC motor.
