Abstract
A power converting device includes a first and a second power module electrically coupled in parallel, a loop current limiting circuit and a driving circuit. A first and a second terminal of the loop current limiting circuit are coupled to the first and the second power module respectively. A third and a fourth terminal of the loop current limiting circuit are coupled to each other. The loop current limiting circuit includes a coupled differential-mode inductor, a first inductive unit and a second inductive unit. A first winding and a second winding of the coupled differential-mode inductor are coupled to the first and the second power modules respectively. The first and the second inductive units are coupled to the first and the second power modules respectively. The driving circuit is configured to output a driving signal to the first and the second power module according to a current detecting signal.
