A CHANGE METHOD OF THE CAPACITANCE VALUE OF THE OUTPUT CAPACITOR OF THE POWER FACTOR CORRECTOR AND AN APPARATUS THEREOF

摘要

The present invention relates to a method of changing the capacitance value of the output capacitor of a power factor corrector. It includes a step of applying AC power to a power conversion circuit, a step of detecting the generation of instantaneous interruption in the AC power, a step of connecting in parallel the output capacitor of the power factor corrector (PFC) of the power conversion circuit when instantaneous interruption is not generated in the AC power, and a step of increasing the capacitance value of the output capacitors by connecting in parallel the output capacitors.
