Abstract:
1. A power regulating apparatus, which is connected between an AC power and a DC load, for regulating the AC power and transmitting the regulated AC power to the DC load, the power regulating apparatus comprising: a first regulating means, provided with an input terminal connected with the AC power, regulating the AC power from an AC power source to a first output AC voltage and/or AC current; an AC-to-DC converting means, converting the first output AC voltage and/or AC current into a second output DC voltage and/or DC current, and providing an output terminal for transmitting the second output DC voltage and/or DC current to the DC load; a power storage means provided for storing or discharging an electric power; and a second regulating means provided with a charging terminal connected with the first regulating means, a discharging terminal connected with the output terminal of the AC-to-DC converting means, and a power access terminal connected with the power storage means, wherein the second regulating means regulates an electric power received from the charging terminal and directs the regulated electric power to the power storage means so as to charge the power storage means, wherein the second regulating means directs an electric power stored in the power storage means to the DC load via the discharging terminal when the AC power is at a power level lower than a normal power level, wherein the second regulating means isolates the connection between the power storage means and the DC load when the AC power recovers to the normal power level.
