Research Institution
40887 November 13, 1996 Advanced Energy Systems, Inc. In photovoltaic energy systems, overcharging can be prevented by using a photovoltaic charge controller to regulate current flow from the photovoltaic array to the battery which stores the charge. This project will design, develop, and manufacture a new type of charge controller for photovoltaic (PV) power systems. The approach combines a DC-DC soft-switched boost converter, a microcontroller "brain", and line-carrier communications capability. Large-scale (> 2 kWp) stand-alone PV systems will have a simpler, more efficient and more reliable way of connecting PV modules to a battery bank. A custom Smart Power ASIC will be used for all analog circuitry, allowing a controller to be made that is small enough to fit inside a standard PV module junction box. Anticipated Results/Potential Commercial Applications as described by the awardee: The results should greatly reduce the cost and complexity of stand-alone PV system balance of system.
