Design and development of three-phase EV charger based on the integration of voltage-oriented pulse width modulation control and water cycle algorithm fractional-order PI controller

ABSTRACT

Increasing gasoline prices and pollution levels make EVs an increasingly attractive and environmentally friendly alternative to gasoline. This paper presents an efficient charging solution for EVs based on the integration of voltage-oriented pulse width modulation (VOPWM) control and water cycle algorithm (WCA) fractional-order-PI (FOPI) controller. A novel control method with integrated VOPWM and an additional degree of freedom FOPI controllers with WCA is proposed to ensure effective charging. The WCA approach optimises the parameters of the FOPI controller. The whole design process for a three-phase EV charger is outlined in this article, emphasising control algorithms.

The charger is designed for a three-phase power supply with a phase voltage of 230Vrms, 50 Hz, and a range of 6.6 kVA. The conferred topology is modeled in MATLAB–Simulink to demonstrate its performance. In a laboratory prototype, experimental results are presented to validate the aforementioned functionalities and to demonstrate the effectiveness of the proposed control scheme.
