Abstract
A control method for use in a primary side power converter () of an inductive power transfer (IPT) system. The power transfer from the primary side to one or more secondary pick-ups is monitored, and the operating frequency of the primary side power converter () is varied in proportion to a difference between the monitored power transfer and a power capability of the primary side power converter. The frequency variation can be sensed by the or each pick-up () to regulate the power transfer and to prevent overloading from occurring.
