Implementation of CSI-Fed Brushless DC Motor Drive using Space Vector Modulation Strategy

چکیده مقاله

Todays, the brushless DC motors (BLDCs) have been widely used in industry and consumer application due to their unique advantages. These motors are generally supplied from voltage source inverters (VSIs). These inverters have a very simple structure, but have problems such as unwanted short circuit across dc-bus and using bulky capacitor in the dc-bus. Using the current source inverters (CSI) is the one of ways to reduce the mentioned problems in VSI-BLDC motor drives. In this paper, the space vector modulation (SVM) strategy is employed for switching in BLDC motor drive supplied by CSI in order to reduce the switching losses and increase the reliability. An experimental setup system is designed and implemented to evaluate the motor behavior at different speeds.
