Performance Analysis of Zeta Converter for Photovoltaic Powered Micromobility Charging Station

Abstract

This paper investigates the use of a Zeta converter in a micro mobility charging station. The system is supplied by a Photovoltaic (PV) panel and the energy is stored in a Li-Ion battery connected to a DC bus. Since the charging station is highly affected by the weather conditions, the performance of the system is evaluated under different irradiance levels and cell temperatures. In addition, the effects of parasitic resistances on the system efficiency are evaluated. The results highlight that the presence of parasitic resistances leads to higher ripples in the power output, indicating reduced efficiency and stability. Various irradiance profiles were applied to assess the system's performance, incorporating a battery load for practical relevance. The Perturb and Observe Maximum Power Point Tracking (MPPT) technique has been employed to optimize power generation. The entire study was simulated using MATLAB/Simulink, enabling a comprehensive evaluation of the PV system's behavior.
