Abstract

There is disclosed a system (10, 100) and method (1000) for controlling electrical power delivered from a renewable energy source (12, 112) to a load (14, 114). The system may include a boost circuit (38, 138) configured to receive electrical power from the renewable energy source and to boost a voltage of the received electrical power by multiplying its voltage by a factor (192) to yield a higher voltage greater than a voltage of a maximum power point of the renewable energy source. The system may further include a buck circuit (40, 140) that has an input for receiving the higher voltage and an output for delivering an output voltage of the buck circuit to the load. The buck circuit may be configured to reduce its output voltage, so that the output voltage of the buck circuit is closer to the maximum power point.
