A Novel Circuit Topology for Vehicle to Load(V2L) Application

Global warming and pollution are big challenges for living beings. It is necessary to decarbonize the energy system by increasing the number of electrical vehicles (EVs), which reduces dependency on internal combustion (IC) engines as well. As EVs grow in number, it brings new challenges for power systems. To neutralize the energy system, the charging and discharging of EVs would be supportive for electricity grid operators by reducing some loads on grids. Vehicle to load (V2L) is the concept of discharging the EV’s battery with domestic loads. V2L technologies add rapid development to the electrification of the transport sector.This paper contains a novel circuit topology that helps EV batteries discharge through domestic loads. By making some modifications, it can also be used for vehicle-to-everything (V2X) applications. This topology has multiphase, multistage boost operation with a d-q-controlled H-bridge inverter to get sinusoidal AC output. The circuit is simple, non-isolated, and cost effective with better efficiency. A 1. 1kW discharging power operation is obtained in a MATLAB simulation to understand the concept of the proposed circuit topology.
