ISOLATED DC/DC CONVERTER USING FULL-BRIDGE TOPOLOGY

摘要

PURPOSE: An isolated DC/DC converter of a full-bridge type is provided to isolate input DC power and output DC power by using a transformer. CONSTITUTION: A full bridge switching unit(110) includes four switches(111-114) which alternatively supplies input DC power to both sides of an input side coil(121) of a transformer(120). The transformer includes an input side coil and an output side coil(122) which outputs the boosted power. A rectifier(130) a first diode(131) and a second diode(132) for rectifying the boosted power. An output unit(140) comprises a first capacitor(141) and a second capacitor(142) for generating the output DC power.
