Abstract
Briefly described, the invention provides a photovoltaic assembly power output utilizing device which partially charges a capacitor assembly. This capacitor assembly is then partially discharged by a DC/DC power converter in different ranges of voltages in which the power output from the photovoltaic assembly peaks for different light intensities.
Claims18
A photovoltaic assembly power output utilizing device, comprising:
- a photovoltaic assembly having a power output, said power output having at least one peak power output value;
- a super-capacitor assembly, having an adjustable input voltage and capable of being partially dischargeable and an output DC/DC converter;
- and,
- an electronic control circuit for charging the super-capacitor assembly by the photovoltaic assembly and then partially discharging the super-capacitor assembly, said charging occurring in a photovoltaic assembly output voltage range wherein said at least one peak power output value occurs, and wherein the DC/DC converter is selectively turned on by the electronic control circuit when a peak power output value has been reached, and wherein the DC/DC converter is turned off when an output power and an output voltage are decreasing at the same time.
