Simulation and Analysis of Single Phase Bi-directional Totem Pole On-board Charger
摘要
In the contemporary era, the global rise of two-wheeler electric vehicles has become pivotal for sustainable development and energy conservation. The necessity for an efficient and effective charger for these vehicles is evident. While numerous two-wheeler electric vehicle chargers are available in the market, this research paper introduces a novel on-board charger tailored specifically for two-wheeler vehicles. This research paper proposes a novel model for an Electric Vehicle (EV) charger comprising a totem pole converter, aimed at enhancing efficiency and performance. The model integrates three key elements: the grid, the on-board charger and the EV battery. Utilizing a totem pole converter for AC to DC conversion, the charger achieves superior efficiency compared to traditional boost Power Factor Converters (PFC). The totem pole configuration optimizes power factor correction and ensures galvanic isolation between the battery and the grid. The paper presents a detailed working principle of the charger, simulation methodology implemented in MATLAB Simulink and analysis of results obtained. Notable findings include stable capacitor voltage, synchronized grid voltage and current, consistent battery terminal voltage and reliable charging current, all crucial for efficient and controlled charging processes. The research contributes to advancing EV charger technology by introducing a totem pole converter and providing insights into its performance and effectiveness. The presented findings suggest that chargers of this nature are poised to gain popularity in future, addressing the growing demand for efficient and sustainable charging solutions for two wheeler electric vehicles.
