Abstract

An inductive power transfer (IPT) converter has a first switching means adapted to produce a time varying input power signal comprising a substantially unipolar stepped waveform, and a second switching means adapted to modify the time varying input power signal provided by the first switching means to produce a modified input power signal. The converter is coupled to a resonant circuit to receive the modified input signal.
