Abstract. This paper presents the design and simulation of a bi-directional battery charging and discharging converter capable of interacting with the grid.
First the bidirectional AC-DC converter operates in two modes, namely as front-end rectifier when power transfer is from the single-phase grid to the EV battery, and it works as a voltage source inverter while the EV battery is pushing back power to the source .
Bidirectional converters stand as the fundamental technology, empowering vehicles to transform into dynamic mobile energy storage systems. With chargers capable of seamless power transfer in both directions, EVs transcend their conventional role as mere vehicles, evolving into integral battery storage units for intermittent energy sources.
In recent times, there has been a notable surge in interest towards bidirectional power flow between the grid and EV batteries. Bidirectional converters stand as the fundamental technology, empowering vehicles to transform into dynamic mobile energy storage systems.
