A dual output buck-boost (DOBB) DC-DC converter is proposed for solar photovoltaic (SPV) array using permanent magnet brushless DC (BLDC) motor drive. To design a DOBB converter with suitable voltage control, DC-DC boost and buck converters are cascaded such that it accomplishes the purpose of maximum power point tracking (MPPT) and soft starting of BLDC motor. The DOBB converter exhibit the advantages about both the buck and boost converters and gives solution to the problem associated with these converters in SPV applications. The good switch utilization, high efficiency, noninverting output voltage and low stress on power devices are the features of DOBB converter. In DOBB converter consists of balancing capacitor so steady state performances can be maintained under varying atmospheric conditions and examines the effectiveness of the BLDC motor from SPV array. Instead of B6 inverter B4 inverter are used so that switching losses can be reduced. The
performance of projected drive is simulated in MATLAB/SIMULINK atmosphere.
