Abstract
An inductive power transfer system comprising a primary inductor wired to a transmission controller and a power supply via a driver, and operable to inductively couple with a secondary inductor wired to an electric load via a reception circuit. The transmission controller instructs the driver to apply an oscillating driving voltage to said primary inductor in an intermittent pattern comprising an alternation of the driver being in an ON state and an OFF state, characterized by a transmission requirement profile. The level of power transmission during the ON state may be the power level at which the inductive power transfer system transfers power with high efficiency. The reception circuit may comprise a power storage element configured to store power received by said secondary inductor when said driving voltage is applied, and to provide power to said electric load.
