Document Type and Number:
WIPO Patent Application WO/2016/098538
Kind Code:
A1
Abstract:
This insulation type step-down converter includes first and second step-down transformers (2A, 2B), and each of the first and second step-down transformers includes an input-side coil and output-side coils. First, second, third, and fourth rectifying elements (31A to 31D) are respectively connected in series to first, second, third, and fourth series coils to which the output-side coils of the first step-down transformer (2A) and the output-side coils of the second step-down transformer (2B) are connected in series, respectively. The first to fourth series coils are connected to smoothing coils (42A, 42B). Connection is provided such that currents flow simultaneously only through, alternately, one of the first and second series coils and through, alternately, one of the third and fourth series coils, and such that the currents which simultaneously flow through two of the one of the first and second series coils and the one of the third and fourth series coils are in opposite directions to each other.
