Regular Extreme Fast Charging Station for E-buses with Low Current Harmonic Content

Year: 2025

Type: article

Abstract: Public transport vehicles based on electric vehicles are suitable for regular extreme fast charging (R-XFC) with supercapacitors as energy storage. Quick recharges cause power quality problems such as high harmonic injection. In this sense, grid-connected converter solutions must address this issue. The main objective of this paper is to present a solution for R-XFC stations with the Zero Harmonic Distortion (ZHD) Converter. The ZHD converter features elements consolidated in the industry and it does not need capacitive filters in the point of common coupling (PCC) with the grid, presenting sinusoidal currents with low harmonic content for regular extreme fast charging (R-XFC) stations. Hardware-in-the-loop (HIL) simulation results of an extreme fast recharge showed a total demand distortion (TDD) of 0.54 %, and experimental results of a 280 kVA prototype had a TDD of 2.29 %.
