Abstract
A current detection circuit can minutely adjust characteristics when currents flowing in two directions in a current transformer are detected. The current detection circuit is configured to detect a value of a switching current through a detection resistor using a current transformer, and the value of the switching current is detected by switching the detection resistor and a reset resistor on the basis of a flow direction of the switching current flowing on a primary side of the current transformer.
