An arrangement for converting an AC supply to a DC supply comprising an inverter circuit and a boost power factor correction stage. The inverter circuit comprises switchable components and utilizes a pulsed waveform indicative of power factor correction for causing some at least of the components repeatedly to adopt a condition permitting the boost power factor correction stage to draw current from the AC supply.
