摘要： The present invention relates to a power supply for controlling current that uses a flyback converter for electrical insulation between a load line unit and the power supply for controlling current. In a transformer (a flyback converter) having a flyback structure in the present invention, disclosed is a device which expects a current of the second coil by sensing a current of the first coil of the transformer, and controls the current flowing through the load line unit. A level detector is included, which updates a duty time or an on-time of the switch by transferring a reset signal to an integrator and a second sampler in accordance with a cycle of an input power. As a result, it is possible to reduce power loss by increasing a power factor through the adjustment of the phase of the current of the load line unit and an input voltage.
