Description
Summary:This work proposes a switched/modulated capacitor filter approach for optimizing electric vehicle (EV) and vehicle-to-house (V2H) battery-charging stations. The proposed method employs using classical optimized Type- 2 Fuzzy Logic Controller. Multi-mode charging modes are modified to enable super-fast charging and enhanced power quality while reducing voltage transients on the DC side, inrush currents and harmonics on the AC side. An inter-coupled AC-DC capacitor interface equipped with dual complementary switching modes is utilized by the modulated filter to enable capacitive compensator pulsing and dual operational modes for the tuned arm filter. The aim of the proposed switched inter-coupled AC-DC filter compensation strategy is to achieve EV-enhanced electrical power usage by mitigating AC-DC voltage transients and inrush currents. The paper presented a dual action switched capacitors-tuned filter and reactive compensator scheme. The dual action complementary switched filter/capacitor compensator is controlled by a multi loop regulation controller to ensure effective measured action based on the global errors sum of the voltage and current/power loops. The novelty of the paper lies in using a multi loop weighted error action to carry the Pulse-Width Modulation (PWM) power width modulation - duty cycle ratio based on slow changing dynamic/inrush loads. Results show the importance of the proposed scheme for improving the overall system efficiency and quality. The proposed scheme is tested and validated under different operating conditions and proved its effectiveness for various conditions.
