Abstract/Summary
This product is a redesign of a DC-DC buck-boost converter which utilizes a new topology, the flyback converter, for use in an electric vehicle (EV) as a microgrid. The main driver behind the redesign is to provide electrical isolation between elements in the microgrid. The EV microgrid consists of the battery, motor, external DC and AC ports, and the power electronics (DC-DC converter and AC-DC inverter) which were designed and built in previous senior projects. Using EV’s as microgrids can help relieve stress from the main power grid caused by charging electric vehicles. Implementing EV’s as a microgrid enables the vehicles to interface with outside sources and loads directly, eliminating the need for additional power electronics such as charging stations, thus increasing total power efficiency. This flyback converter takes power from outside DC sources, such as solar, to charge the battery of the EV, as well as peer-share power to other EV’s using the main battery of the microgrid EV. By using a flyback converter in the EV microgrid, the safety of the entire system will improve and the microgrid will support interfacing directly with outside loads and sources.
