Title
Performance Improvement Of Solar Pv Power Conversion System Through Low Duty Cycle Dc-Dc Converter
Abstract
Characteristics like reliability and modularity of solar photovoltaic (SPV) units makes them one of the apt options for generating electric power. However, the input intermittency is their major lacuna, and power electronic circuits are being used to nullify this effect. A solar photovoltaic power conversion process includes a DC-DC converter in the plant side to deliver a fixed DC voltage and a DC-AC converter in the grid side for converting DC voltage in to grid compatible AC voltage. The high duty ratio of typical DC-DC boost converters limits the switching frequency and efficiency. In this article, a way to enhance the performance of a SPV unit using an improved quadratic boost converter (IQBC) is analysed. It can deliver a higher output voltage at lower duty ratio with Perturb and Observe (P&O) algorithm-based Maximum Power Point Tracking (MPPT). A 250 W prototype of IQBC-based Solar PV power conversion system (SPVPCS) is developed, and its performance is compared against conventional and quadratic boost converters and found that the IQBC-based solar power conversion system is efficient and the results are presented.
