The chapter proposes the design of a sliding mode controller for power converters in supercapacitor charging applications for electric vehicle charging stations. The model of the system to be controlled is composed of a Buck power converter model, and the classic supercapacitor model is considered the load, whose parameters are known. Thus, the model obtained is subsequently used to design a switched discontinuous sliding mode controller that accelerates the charge of the supercapacitor. The proposed algorithm can guarantee the supercapacitor's charging by monitoring its voltage, which can be reconstructed using the voltage in the buck converter's capacitor and the supercapacitor's current. The results are validated through simulation.

摘要

The chapter proposes the design of a sliding mode controller for power converters in supercapacitor charging applications for electric vehicle charging stations. The model of the system to be controlled is composed of a Buck power converter model, and the classic supercapacitor model is considered the load, whose parameters are known. Thus, the model obtained is subsequently used to design a switched discontinuous sliding mode controller that accelerates the charge of the supercapacitor. The proposed algorithm can guarantee the supercapacitor's charging by monitoring its voltage, which can be reconstructed using the voltage in the buck converter's capacitor and the supercapacitor's current. The results are validated through simulation.
