A New Vector Control for Brushless DC Motor Using Effective Photovoltaic Power Source

Abstract

In increasing demand of non-renewable power source, renewable power generation is create impact on power demand. PV (Photovoltaic) source is having notable merits such as noiseless, pollution free and high efficient power generation over wind power generation. This paper proposed a sensor less vector control of Brushless DC (BLDC) Motor using space vector Pulse width modulation generation. Photovoltaic power sources is used for supplying power for brushless DC drive and power generation capability of PV (Photovoltaic) is improved by fuzzy logic based maximum power point tracking scheme is proposed in this paper. Proposed MPPT is a modified form of incremental conductance and its overcome demerits such as extraction in local area, extended commutation time of solar array. The control and estimation of parameters are effectively derives in proposed vector control scheme without need of additional loops. The enhanced of proposed scheme is implemented using MATLAB/Simulink results.
