【摘 要】

In the Inductive Power Transfer (IPT) common energy launch platform for kitchen appliances, a low efficiency will appear under some light loads. In order to make the designed IPT system achieve the high efficiency under all different power capacity levels, the main losses of selected IPT system have been analyzed and then the efficiency calculation model is presented. Then, the control strategy of efficiency optimization as well as the segmented optimal frequency dynamic tracking method has been proposed. Finally, experimental results show the overall efficiency of IPT system for kitchen appliances using the proposed control strategy is increased significantly under all light loads. Meanwhile, the reliability and stability of system under heavy loads aren’t declined.
