The system includes a first stage of an inductive power transmission system including a switching unit, an LCL tuning circuit, and an LCL load resonant converter with a primary receiver pad. The IPT system includes a second stage including a secondary receiver pad, a secondary resonant circuit, a secondary rectifier circuit, and a secondary decoupling converter. The secondary receiver pad couples to the secondary resonant circuit. The resonance circuit is connected to the secondary rectification circuit. The secondary rectifying circuit connects to the secondary decoupling converter. The second stage connects to the load. The load includes an energy storage element. The second stage and the load are installed in a vehicle, and the first stage is installed in a fixed position. When the vehicle places the secondary receiver pads with respect to the primary receiver pads, the primary receiver pads wirelessly transmit power to the secondary receiver pads across the gaps. |
