Abstract
An inductive power transfer (IPT system) includes an AC-AC full-bridge converter (Tp1-Tp4) provided between the primary conductive path (Lpt) and an alternating current power supply (Vin). The system may include a controller for controlling the pick-up device to shape the input current drawn from the alternating current power supply (Vin).
