DescriptionModified sine wave inverter waveform.png
English: Waveform of an automotive inverter producing 120 V AC, approximately 60 HZ|, from the vehicle's 12 volt cigarette lighter power outlet. This three-step waveform uses alternating positive and negative pulses to approximate the peak to peak and RMS values of a sine wave. A simple circuit can be used because only two voltage levels are required.
