| Abstract |
This paper presents a high-efficiency switch-mode circuit that will extract maximum power from a PV array. Circuit operation is based on the observation that the voltage across a photovoltaic cell at maximum power output is a nearly constant fraction of the open-circuit voltage. In addition, this proposal uses a minimum of both small signal and power components, which is important in all applications. In particular, this paper shows that an energy storage capacitor is unnecessary for a PV controller provided a step-up switch-mode controller is used. |
