<p>A circuit receives variable voltage and current from a renewable power source and optimally loads the source to maximize power delivered into a DC bus having constant voltage. A boost circuit and synchronous rectifier having a controlled duty cycle step up the voltage from the renewable source. A feedback control circuit senses delivered current and optimizes the duty cycle to maximize this current, and therefore maximize delivered power. Precision measurement of delivered current is not necessary, greatly reducing complexity and expense. The power source can be isolated from the DC bus, and an arc fault sensor can determine the presence of an electrical arc and shut down the power conditioner to prevent damage due to arcing or fire.</p> |
