> What is the isolation between the DC and AC circuits? No safety isolation is necessary between the automobile DC and the inverter output AC. Indeed, for most inverters, safety isolation would make the inverter much larger and more expensive.
Inverters generate plus and minus high voltage steps with respect to the DC. The steps approximate the energy-time content of a sinusoidal waveform. Such circuits cannot have one AC pole connected to the DC common. The AC output socket should be an earthing type. The earthing terminal of the socket should be connected to the common pole of the car's DC. This creates the equipotential environment with respect to the metal of the car.
