Abstract
The principle of digitally synthesized AC voltage standards is well established. This paper describes a new AC voltage standard which uses a traceable DC voltage standard as an input and produces an AC output at an equivalent RMS voltage to 1 μV/V uncertainty. The system works using digital synthesis with a so called Pulse-Width Modulator (PWM) Digital to Analog converter (DAC)
