Abstract

Renewable sources like solar photovoltaic (PV) are preferred to be operated at low voltages. This necessitates high voltage boosting when they have to be connected to the high voltage DC bus. Conventional DC-DC converters (eg. boost and buck-boost) offer high voltage gain at the cost of reduced efficiency. This paper proposes a novel method to integrate low voltage PV power to the high voltage DC bus using a simple boost converter. The analysis of the proposed topology and control strategies are discussed. Simulation studies are carried out in MATLAB/SIMULINK and results for the same are presented.
