Abstract
Disclosed is a power regulating apparatus, which is connected between an AC power and a load, for supplying the regulated AC power to the load. The power regulating apparatus includes a first regulating means provided to regulate the input AC power source when the AC power is at a normal power level, and a second regulating means provided to transmit an electric power to the load from a power storage means when the AC power is at a power level lower than the normal power level. Thus, the power regulating apparatus is capable of providing the load with an expected high quality electric power in all cases of AC power variation.
Claims16
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.
A power regulating apparatus, which is connected between an AC power and an AC load, for regulating the AC power and transmitting the regulated AC power to the AC 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 power controlling means provided for transmitting the regulated power having the first output AC voltage and/or AC current or an AC electric power converted by a DC-to-AC converting means to the AC 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 an output terminal of the DC-to-AC converting means, and a power access terminal connected with the power storage means,
- wherein the DC-to-AC converting means converts a DC voltage and/or a DC current into the electric power having AC voltage and/or AC current, and directs the AC electric power to the AC power controlling 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 AC load via the DC-to-AC converting means 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-to-AC converting means when the AC power recovers to the normal power level.
