Evaluation of wireless charging systems from the point of view of energy transfer in electric mobility

A basic wireless charging system consists of some essential components as shown in Figure 1.1 The AC current power supply coming from the grid is converted by an AC converter into a DC current power supply. At this point the rectified current is converted via an inverter into high frequency AC to drive the transmission coil through a compensation network. The high-frequency current in the transmission coil generates an alternating magnetic field, which induces an alternating voltage on the receiving coil. At the end, the AC power supply is rectified to charge the battery.
