研究目的
To propose the significant usage of photovoltaic modules in household applications by integrating basic converters to form a simplified single inductor converter structure while keeping minimum number of switches.
研究成果
An effective power flow can be attained by using a single inductor integrated in three port converters between the source, battery and load. By neglecting the transformers and full-bridge converter, the system becomes compact and Switching losses are be minimized by implementing Zero voltage crossing technique. The efficiency is further increased by controlling through variable step size P&O algorithm. The experimental verifications also show the efficient optimization of photovoltaic energy in all six modes and all the modes becomes easily reconfigurable when using single inductor.
