Abstract
This research thesis presents a study and analysis of an on-board charger for Electric Vehicle through different topologies simulated using MATLAB Simulink to select the best topology for high power demanding vehicles such as electric trucks. The concept also consists of mitigating the risk of harmonics and improving the power factor at the grid side during energy conversion from AC power to DC power because an electric vehicle behaves as a nonlinear load during charging which creates harmonics to the power supply. The presence of harmonics in the power supply impacts efficiency and degrades the performance hence the need to apply power factor correction and voltage regulation to provide suitable power to the vehicle’s battery pack.
The first stage of energy conversion is the AC-DC conversion. This can be done through several topologies such as interleaved boost power factor correction (PFC) PFC, totem-pole PFC converter, dual active boost PFC converter to achieve high power factors in continuous conduction mode.
The second stage consists of ensuring a DC-to-DC conversion while regulating the DC output to the proper voltage and current level for the battery. In fact, there are numerous technologies to accomplish it which means for this study, we will be reviewing state-of-the-art topologies, their different specifications, domain of applications and limits in the fast-charging techniques. The goal is to identify which topologies are good for high power applications. The proposed models for each stage are used to lead a comprehensive study to establish a comparison according to their performance, efficiency and power rating and finally end with a case study whose given specifications are such as minimum load power equals to 30kW, 230V AC input, 380V DC link voltage, and 450V output voltage to charge the EV’s battery pack.
