3상 영구자석형 브러시리스 전동기 구동에 적합한 구형파 SVPWM 제어기법의 제안

In this paper, the rectangular space vector PWM control algorithm suitable for 3 phase PM-BLDCM drive is proposed on the based of conventional sinusoidal SVPWM for IM or PMSM drives. Compared to a conventional rectangular PWM control scheme by triangular comparison, the proposed rectangular SVPWM control scheme is simpler and can be easier embedded in the digital control system. And this scheme has advantages to reduce torque ripple of PM-BLDCM. These effectiveness will be verified through analyzed simulation results using PSIM.
