An inverter is a device that converts direct current (DC) from the EV’s battery into alternating current (AC) to power the electric motor, as most EV motors operate on AC. The inverter also plays a role in converting AC power back into DC when the vehicle is braking and using regenerative braking to recharge the battery. Inverters are a critical component of electric vehicles because they manage the flow of electricity to ensure efficient operation of the motor and other electrical systems.
