力ＤＣ／ＤＣコンバータ。[Claims for Utility Model Registration] A transformer having a primary winding and a plurality of secondary windings, a switch circuit that turns on and off an input DC voltage to the primary winding, and each of the two In a multi-output DC/DC converter equipped with a rectifying and smoothing circuit that rectifies and smoothes the AC voltage obtained in the secondary winding, a converter for detecting load current is installed in series with each of the secondary windings. The characteristic value di/dt of the output of each current transformer is di/dt〉
For an output that is 0, the output is rectified by a diode, and for an output that is di/dt<0, the output is rectified by a diode, and a resistor or inductance is connected in series with the rectifier diode. A multi-output DC/DC converter characterized in that a detection signal for overload protection is obtained through each.
