| Summary: | This paper aims to design and simulate a Wireless Power Transfer charger that can achieve fast charging, thereby improving the EV users’ experience and bypassing the disadvantages of Level 1 and 2 chargers. We attend to this objective by presenting a Two-Stage Inductive Power Transfer system controlled by the constant power (CP) control strategy. Key innovations include the integration of an LCC-C compensation network with a Switched-Controlled Capacitor (SCC) and a DC/DC Buck converter. To validate our proposed system, we simulate a prototype using SimScape library. The simulation leads us to design a TSIPT prototype that achieves high-power charging of 15.3 KW and a power efficiency ranging from 92.2 % to 88 %, and an output voltage varying from 523V to 878V. These results are thanks to the DC/DC Buck converter that regulate the output and help to improve the battery life span, and due to the combination between the SCC and the secondary active rectifier (AR) the proposed IPT can maintain with a maximum constant charging output and a maximum power efficiency, that can make the overall system more stable. |
