Title:
DC/DC CONVERTER
Document Type and Number:
Japanese Patent JP2015116017
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a DC/DC converter capable of easily reducing noise when a switching element is switched to an on-state.SOLUTION: Respective one ends of a switching element Q1, a diode D1, a coil L1 are connected to one another, to a connection portion of which one end of a capacitor C2 is connected. A control unit 50 controls a gate voltage of the switching element Q1 in a manner such that a current flowing through the switching element Q1 to be detected by a first current detection unit 30 when the switching element Q1 is switched to an on-state becomes a current which is obtained by adding an off-set current to a current flowing the coil L1 to be detected by a second current detection unit 40.
