Abstract (en)
[origin: WO8700312A1] An electronic control circuit for use with a varying power supply (21) such as the output from a solar collector or wind generator and a load (22) such as a battery being charged by the power supply, provides two forms of control for maximizing power transfer. Firstly, an inverter (20) with varying duty cycle is connected between supply and load and the circuit controls the duty cycle thereof to maximize power transfer and secondly a stepper motor (25) is connected to the supply to physically alter the power provided by the supply by, in the case of a solar collector for example, altering the angle of the collector relative to the sun. The cirucit compares successive measurements of the output power and generates control signals to alter the angle of the collector and modify the duty cycle. The circuit is adapted to calculate the mean maximum power position. Limit detection is included to prevent latch-up and a voltage regulator is included to override the system.
