Abstract: This paper refers to the design and control of a standalone solar-photovoltaic (PV) energy system using an isolated half bridge boost DC-DC converter. The adaptive methodology-based incremental conductance (INC) scheme is used with the proportional integral (PI) controller for maximum power point tracking (MPPT) control. A voltage controller and current regulator are designed for VSI using a cascade loop control to sustain the power quality at the consumer load side. The proposed system with its controllers is modelled in MATLAB and its results are assessed under varying solar radiations in addition to varying consumer loads.

Keywords: adaptive INC MPPT controller; closed loop controller; DC-DC converter; maximum power point tracking; MPPT; solar photovoltaic.
