ABSTRACT:
A duty control circuit for controlling a duty factor in various industrial applications is proposed. It comprises a n-pulse counter, a m-pulse counter, another n-pulse counter, and a magnitude comparator. The magnitude comparator compares the count of the first counter with the count of the third counter and the duty control circuit gives a signal corresponding to ON when the former is larger than or equal to the latter and a signal corresponding to OFF when the former is smaller than the latter.
