Solar PV Array fed Modified PMBLDCM Drive Scheme for Blower Applications

A solar PV array fed PMBLDCM drive system for blower applications is presented in this paper. The power optimization of the solar PV array is done using modified DCDC converter based MPPT technology. The scheme is efficient, reliable and suitable for rural areas where the grid supply is limited. The PMBLDCM based blower is also works during bad weather conditions at lower speed. The scheme found highly suitable due to various advantages like wide MPPT operating range, simple configuration and high efficiency. The scheme is simulated and tested at various operating conditions (steady state and dynamic) and at different environmental condition (different insolation levels). The results validate the suitability of the proposed system for solar powered blower application.
