摘要： PROBLEM TO BE SOLVED: To provide an insulting type converter which is suitable for a large output current and a synchronous rectifier circuit while excellent in quick response to an abrupt load change. SOLUTION: A choke 2 of a forward converter is shifted from a secondary side to a primary side. The current of the choke 2 is distributed between a plurality of transformers 31 and 32, and then transferred to the secondary side. This distribution is performed to prevent the saturation of the transformers 31 and 32. A flywheel diode is also shifted to the primary side along with the choke 2. In such application as with much less current on the primary side than on the secondary side, a high efficiency is attained even if the flywheel diode is not synchronously rectified with no possibility of flowing of a through current.
