APPARATUS FOR POWER FACTOR CORRECTION AND METHOD FOR POWER FACTOR CORRECTION USING THE SAME

摘要

The present invention relates to a power factor correction apparatus and a power factor correction method using the same. The power factor correction apparatus according to an embodiment of the present invention includes a power factor correction circuit and a control circuit. The power factor correction circuit includes a first and a second inductor which are connected to an input power terminal, and a first and a second main switch which perform switching operation for the first and the second inductor, respectively. The control circuit provides a control signal to each of the first and the second main switch. When the phase of the first and the second inductor current which flows along the first and the second inductor is unbalanced, any one of the first or the second main switch changes at least one phase of the first or the second main switch to correct the imbalance.
