Abstract
The invention relates to inductive power transfer (IPT) systems, and has particular relevance to control of IPT systems, and to operation of IPT system primary power supplier. There is provided a method for controlling an IPT system primary power supply having a switched resonant circuit; the method comprising: determining the value of a parameter of the system; determining an energy injection switching pattern having a duration dependent on the parameter value; controlling the resonant circuit according to the determined energy injection switching pattern.
