DSP Implementation of a Power Factor Correction Strategy for BLDC Motor Drive
The paper develops a power factor correction mechanism for a brushless dc permanent magnet (BLDC-PM) motor drive system through the use of a front end boost converter. It evolves a wave shaping mechanism to arrive at the sinusoidal nature for the input current in an effort to improve the input power factor. The theory is articulated using a closed loop algorithm to revolve around the operating range of the drive motor. The performance is evaluated on a MATLAB platform to elucidate the viability of the scheme in addition to highlighting its speed regulating capability. It steals the role of a Digital Signal Processor (DSP) to implement the proposed methodology and there from validate the results with a view to illustrate its practical applicability.
