A CHARGING MODULE OF ENERGY STORAGE DEVICES

摘要

PURPOSE: A charging module of an energy storage device is provided to improve the life span and reliability of an energy storage device by stably supplying power required for charging the energy storage device without using an electrolytic condenser. CONSTITUTION: A charging module(100) of an energy storage device comprises a rectifier unit(110), a power factor correction circuit(120), a DC/Dc converter(130), and a capacitor(150) for DC link. The rectifier unit rectifies single-phase AC power inputted from the commercial line to obtain DC voltage. The power factor correction circuit controls input current into sine waves. The DC/DC converter supplies power necessary for a load(140) to charge. The capacitor for DC link controls the voltage outputted from the power factor correction circuit and transmits the controlled voltage to the DC/DC converter.
