摘要： A method of measuring the d.c. level in the output of an a.c.-to-d.c. power converter provides the accurate measurement result with a minimal time lag for the measurement and without the need of changing the operating parameters depending on each ripple frequency by the averaging process for the ripple component included in the d.c. output over certain periods of the input power frequency.
