| Summary: | This paper presents an Inductive Power Transfer (IPT) system design using a Class E converter
circuit. The Class E converter is used to drive a nonlinear load and theoretically it offers 100% efficiency. To
be specifically, the performance of IPT system at 1MHz operating frequency and 9V DC supply voltage is
analyzed. Voltage doubler rectifier and Darlington circuit are proposed in this paper to maximize output power.
Moreover, to ensure the resonant inductive coupling in IPT system,capacitor compensation is also proposed in
this work. Based on the experimental results, the output power with the capacitor compensation circuit is 1.6W
at 15 mm air gap distance is better than the circuit without a capacitor compensation. |
