Abstract
This paper proposes a cost effective photovoltaic (PV) generation system in DC microgrid which is helpful to achieve not only high efficiency but also cost reduction by employing simple control algorithm. While the AC interactive PV interface requires high performance processors for sinusoidal current injection to the grid, only a simple maximum power point tracker can directly control the PV module in DC microgrid without voltage compensator and current injection. Utilizing the unique principle of boundary conduction mode operation, an integrated simple controller for PV power conditioning is proposed. Prototype DC PV power conditioning system is implemented for 120 W building integrated photovoltaic (BIPV) application and experimental results verify its feasibility with MPPT efficiency of 99.9 % and maximum power conversion efficiency of 98.0 %. © 2012 IEEE.
