Abstract：A broadband programmable AC voltage ratio standard based on the combined voltage divider of a two-stage inductive voltage divider and a multiplying digital-to-analog converter (mDAC) is proposed to achieve high-precision arbitrary AC voltage ratio output within the operating frequency range. The ratio standard adopts the self-locking relay switch to realize the programmable control of the two-stage inductive voltage divider, and uses the injection voltage method to realize the combined voltage division of the mDAC and the two-stage inductive divider. A broadband mDAC ratio error correction method is proposed, which improves the accuracy of the ratio standard by an order of magnitude. A precision comparison measurement system for AC voltage is proposed, and the performance of the ratio standard is tested. The programmable AC voltage ratio standard output ratio resolution is better than 1μV/V, the in-phase error is better than 0.2μV/V in the operating frequency range of 50Hz~10kHz, and the quadrature error is better than 1μrad at 1kHz.
