Abstract

The paper analyses the SVPWM control schema of three-phase inverter employing 120° switch-on mode, proposes a starting control method combined the SVPWM control schema with current regulation adopting the two-point comparator 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.
