Conclusion

Focusing on electric vehicle inductive battery chargers, one can see that several requirements have to be met. Battery charge modes, robustness of control and electromagnetic compliance are the most important ones but when considering economic aspects, simplicity and reliability become important too. Furthermore, if inter-operability, or standardization, may be reached, chances for ICPT systems being quickly spread in industry, public and private transportation vehicles are real. This paper aims at presenting developed principles tending to bring relevant solutions. Two major innovations are brought. The “Dual-topology” ICPT allows to greatly simplify the embedded electronics by suppressing a DC/DC converter. The “Control-Oriented Compensation” enhances the functioning by avoiding dependencies to the system parameters. Depending on its own requirements, the reader will be able to make the right choices for the development of a wireless battery charger.
