Abstract

The present invention provides a converter circuit (300) and accompanying switch mode power conversion (315) technique to efficiently capture the power generated from a solar cell array (210) that would normally have been lost, for example, under reduced incident solar radiation. In an embodiment of the invention, the converter circuit generates an output current from the solar cell power source using a switch mode power converter. A control loop is closed around the input voltage to the converter circuit and not around the output voltage. The output voltage is allowed to float, being clamped by the loading conditions. If the outputs from multiple units are tied together, the currents will sum. If the output(s) are connected to a battery (220), the battery's potential will clamp the voltage during charge. This technique allows all solar cells in an array that are producing power and connected in parallel to work at their peak efficiency.
