摘要： An electrical circuit for electric vehicle supply equipment, the electrical circuit 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, an isolation unit electrically connected to the pilot control signal unit and a first ground and being structured to isolate the pilot control signal to generate an isolated pilot control signal, and an amplification unit electrically connected to the isolation unit, having a second ground, and being structured to amplify the isolated pilot control signal to generate a pilot signal. The isolation unit is structured to isolate the second ground of the amplification unit from the first ground.
