Abstract
Disclosed is the powder feeder in which the sampling timing G, H, . . . is set during the inactive period T.sub.i in synchronism with the cycle of the duty ratio clock when the output voltage V.sub.CELL is fed back to the microcomputer 13, thereby the feedback signal (the output voltage V.sub.CELL) on which noise is not superposed can be sampled and the feed amount of the powder P can be controlled with high accuracy.
