Solar panel peak power tracking systemPublic
Downloadable Contentopen in viewer
The design of a Maximum Peak Power Tracking (MPPT) controller for a solar photovoltaic battery charging system is proposed utilizing a boost-converter topology. Solar panel voltage and current are continuously monitored by a closed-loop microprocessor based control system, and the duty cycle of the boost converter continuously adjusted to extract maximum power. System testing confirms peak power tracking under changing lighting conditions. Under specific conditions, efficiencies in excess of 90% are shown to be possible.
