摘要： An energy storage system comprises: an alternating-current/direct-current converter; a battery; a booster; a direct-current/alternating-current converter; a power control unit; an inductor having one terminal connected to a supply terminal to which normal alternating-current power is supplied; a switching unit having one terminal connected to the other terminal of the inductor and having the other terminal connected to an input/output terminal; a current determination unit which compares an inductor current flowing through the inductor with a power recovery limit current determined by a user; and a switching control unit.

摘要： In a power saving LED (Light Emitting Diode) display board system, each pixel is formed by combining at least one red LED, at least one blue LED and at least one green LED. The power saving LED display board system includes a power converter; a red LED power supply; a green LED power supply; a blue LED power supply; and a DSP (Digital Signal Processor) for controlling the red LED power supply to convert an electric power supplied from the power converter into a red LED operation power, controlling the green LED power supply to convert the electric power supplied from the power converter into a green LED operation power and controlling the blue LED power supply to convert the electric power supplied from the power converter into a blue LED operation power.
