A control arrangement for use in controlling the electrical supply from a power supply unit including an internal capacitance 16 to an output 30, the control arrangement comprising first and second magnetically linked inductors 24, 26 arranged in series with one another and defining therebetween a connection 40 by which they are interconnected, third and fourth magnetically linked inductors 34, 36 each being connected to the connection 40 between the first and second inductors 24, 26, switch means 52 providing switched connections between the third and fourth inductors 34, 36 and ground, and a controller 50 operable to control the operation of the switch means 52 such that closing of a switch of the switch means 52 results in the formation of an LCR circuit, the internal capacitance 16 forming the capacitance of the LCR circuit and the third or fourth inductor 34, 36 forming the inductance of the LCR circuit, the magnetic link between the third and fourth inductors 34, 36 allowing an output to be generated from the other of the third and fourth inductors 34, 36. The capacitance may be an internal capacitance of the supply unit. The power supply unit includes a pn junction diode. The power supply comprises a solar panel. The third and fourth inductors may be identical or one may be larger than the other. The load may provide the resistance of the LCR circuit. A method of controlling the output of the arrangement is also provided. |
