Zusammenfassung:	A self-powered converter and more particularly, though not exclusively, a step-down voltage converter requiring no external power supply, which is particularly suited to converting a high-voltage, low energy input from an intermittent DC power source to a low voltage DC output. There is provided an electrical converter for converting input power from an intermittent power source to a different voltage for a load, the converter comprising: a switched converter circuit coupled to an input for coupling to the power source and to an output for coupling to the load, the switched converter circuit arranged to convert power from the input to a different voltage and supply this to the output; a controller for controlling the switched converter circuit dependent on an input voltage at the input.
