ACTIVE BLEEDER, ACTIVE BLEEDING METHOD, AND POWER SUPPLY DEVICE WHERE THE ACTIVE BLEEDER IS APPLIED

摘要

An active bleeder according to an exemplary embodiment of the present invention includes a bleed switch coupled to the input voltage and an active bleeding controller generating a bleed reference voltage according to a result of counting a period during which the input voltage is generated and switching the bleed switch according to a result of comparison between the bleed reference voltage and a bleed sense voltage corresponding to a current flowing to the bleed switch.
