BI - Directional Operation of BLDC Motor for Electric Drives

Arya V Kurup

Abstract: Brushless DC (BLDC) Motors have found various applications in industrial and domestic uses. BLDC motor accomplishes electronic commutation, which enables Bi - directional operation of BLDC motor, which appears in drives like Electric Vehicle, lifts and trolley cars which improves efficiency and increases the running period of drives. The speed control in both directions requires a Bi - directional DC - DC converter in between source and the inverter. Many configurations of Bi - directional converters are available in the literature with different characteristics and applications. In this work, a Bi - directional converter is chosen which have more full conversion ratios, reduced voltage stress and with a low component count. MATLAB modelling and simulation studies validate the proposed strategy. The Bi - directional operation and regeneration of the BLDC motor are possible by controlling the current through Bi - directional converter.
