ELECTRICAL POWER TRANSFER APPARATUS |
摘要 |
Electrical power transfer apparatus (40) for controlling the supply of electrical power from an array of photovoltaic cells (41) to an electrical load (46) by means of a switching power converter (45). The switching power converter (45) is controlled by a regulator (58) to maintain the output voltage from the photovoltaic array (41) at a fixed fraction of the open circuit voltage of the photovoltaic array (41), the fixed fraction suitably being between 0.75 and 0.8, whereby the power transfer from the photovoltaic array (41) is maximised. The open circuit voltage of the photovoltaic array (41) is sensed by inhibiting the operation of the switching power converter for short sampling periods at regular intervals, and allowing a capacitor (52) to charge to the voltage of the open-circuited photovoltaic array (41) during the sampling periods. |
