Abstract:
1. An electrical power supply for supplying power to an electrical load, the electrical power supply comprising: a solar panel; an energy storage capacitor electrically coupled to the solar panel; a power conversion system having an input electrically coupled to the solar panel and an output configured to be electrically coupled to the electrical load, wherein the power conversion system is configured to supply power to the electrical load in short-term bursts, wherein each short-term burst includes a first time period in which power is supplied to the electrical load and a second time period in which substantially no power is supplied to the electrical load; and a controller configured to control the power conversion system according to a maximum power point tracking (MPPT) method to substantially maximize the power drawn from the solar panel and exchange power with the energy storage capacitor to maintain the voltage of the energy storage capacitor above a predetermined threshold.
