The main purpose of this study is to describe a low cost four-switch brushless dc motor (BLDCM) drive. An improved direct current controlled scheme is designed and implemented to produce the desired dynamic and static current and speed characteristics. Eight voltage vectors are summarized, which are selected to control BLDCM in SVPWM pattern. This method avoids the undesired current distortion which is caused by uncontrollable phase. The operational principle of the four-switch BLDC motor drive and the developed control scheme are theoretically analyzed and the performance is demonstrated by both simulation and experimental results.
Key words: Brushless dc motor, direct current control, four-switch inverter, voltage space vector, , ,
