ISOLATION DC-DC CONVERTER USING COUPLED-INDUCTOR

摘要

Insulated converter having a coupling inductor according to an embodiment of the present invention is connected in series with a first inductor connected in series with a first terminal of an input power and a second terminal of the input power to be magnetized and coupled with the first inductor. And a coupling inductor composed of the first inductor and a second inductor having positive mutual inductance, wherein the ripple of the output voltage is removed due to the magnetizing inductance and leakage inductance of the coupling inductor, and leakage current can be effectively suppressed. I can.
