Abstract
An electrical circuit for electric vehicle supply equipment including a pilot control signal unit structured to generate a pilot control signal having a state including one of a high state and a low state, a pilot control signal isolation unit structured to generate an isolated pilot control signal that is isolated from the power lines of the electric vehicle supply equipment and is based on the state of the pilot control signal, and an amplification unit structured to generate a pilot signal based on the state of the pilot control signal. The amplification unit is structured to receive the isolated pilot control signal and the isolated voltage and to use the isolated pilot control signal and the isolated voltage to generate the pilot signal, and the pilot signal is isolated from the power lines of the electric vehicle supply equipment.
