Abstract
This study, presents a generalised multi-pulse converter (MPC)-based improved power quality charging scheme for heavy-duty vehicle battery swapping stations. The proposed control is a generalised control, which is used to develop an MPC-based charging scheme for any pulse number such as 2-pulse, 6-pulse, 12-pulse, 18-pulse and 24-pulse charging schemes for heavy-duty vehicle battery swapping stations. The 2-pulse, 6-pulse and 12-pulse charging schemes are implemented in the laboratory using proposed generalised control. This proposed scheme operates on fundamental switching frequency, therefore, it significantly reduces the switching losses, electromagnetic interference, radio frequency interference levels in heavy-duty vehicle battery swapping stations. Moreover, the sliding mode controller has been introduced in the current control loop of the proposed battery charger which removes all the possibilities of the occurring of undershoot and overshoot in the battery charging, that significantly improves the life of the battery banks. Test results of all these developed schemes are presented in this study for validating the proposed scheme.
