摘要: A current detector of an inductive load includes: 100; a switching element 101 connected in series with the and controls electric to be carried through this by ON/OFF operation; circulating diode 102 parallel circulates when is OFF; detecting device 103 making sampling cycle predetermined period detect 101; correction 104 respect value having been detected at detector, which changes rate based on DUTY pulse brought operation.
