Abstract: This paper describes the principle, realization methods of AC voltage standard based on Josephson effect and sources of uncertainty. The performance of AC voltage standard using the methods of synthesis waveforms and pulse-driven is compared. The AC  voltage standard using the methods of synthesis waveforms is applicable to establish low-frequency metrology standard and using the methods of pulse-driven is applicable to establish highfrequency metrology standard.

Key words: Josephson effect, AC Voltage standard, Synthesis waveforms, Pulsedriven
