Abstract

PURPOSE:To reduce a cost and a space by suppressing the leakage of switching noise through one piece of common mode choke common to each DC output by multi-output converter of switching system even if the number of DC outputs increases. CONSTITUTION:A multi-output converter converts AC voltage obtained by switching DC input at a switching section 1 into (n) pieces of AC voltage by a transformer section 2 and rectifies separately by a rectifier circuit section 3 to output (n) pieces of DC voltage V1-Vn to a load through a common mode choke 4. The choke 4 is wound around one piece of common core together with (n) pieces of coil 41-4n inserted separately one by one to (n) pieces of outlet line outputting the DC voltage V1-Vn of output of the rectifier circuit section 3 and one piece of coil 40 common to the outlet lines. And, it has such a construction that the total of each number of turns is equal to that of one piece of coil 40, and the whole coil operates as one piece of common mode choke.
