INTERLEAVED TYPE POWER FACTOR CORRECTION CIRCUIT HAVING TRANSFORMER FORMING SEPERATED WIRING STRUCTURE

摘要

PURPOSE: An interleaved type power factor correction circuit having transformer forming separated wiring structure is provided to reduce parts costs and a circuit area by integrating two inductors which are physically separated in one transformer. CONSTITUTION: A rectifier(110) rectifies AC power. First and second inductor coil is charged or discharged according to the operation of a switch. The bobbin portion has a partition wall which separates the first and second inductor coil. A switching unit(130) switches a power source delivered to the first and second inductor coil. A controller(140) is switched to control the phase difference between the voltage and current of the power to satisfy a set phase difference. A stabilizing portion(150) stabilizes a switched power source.
