OUTPUT AUGMENTATION EQUIPMENT Description:

Technical Field

The present invention relates to an output power boost device, and more particularly, to an output power boost device for increasing rotary power of a power transmission shaft.

A typical engine is a device which converts various forms of energy such as thermal, electrical, or water energy into mechanical power or motion. Usually, gasoline, diesel, or gas is used as fuel for engines.

Background Art

Engines using the fuel have a relatively low thermal efficiency in contrast to their output p.ow r. On the contrary, they generate an amount of harmful exhaust gases caused by combustion of fuel, thus originating air contamination. Recently, there have been various attempts to develop devices for generating or boosting output power by using alternative energy such as solar heat or electricity in a variety of fields. Description of Drawings

The above and other features and advantages of the present invention will become more

apparent by describing in detail exemplary embodiments thereof with reference to the

attached drawings in which:

FIG. 1 is a schematic diagram showing a state that an output power boost device

according to the present invention is installed in a car transmission;

FIG. 2 is a schematic circuit diagram of FIG. 1; and

FIGS. 3 and 4 are circuit diagrams showing two kinds of operation method of an

uninterruptible power supply.

Technical Problem

An object of the present invention is to provide an output power boost device which is

connected to an apparatus requiring mechanical forces to increase rotary power of a power

transmission shaft which transmits power to it.

In order to achieve the above object, an output power boost device according to the

present invention comprises: a motor 11 , which comprises a connecting shaft 13 in one side

and a power transmission shaft 12 in the other side; a generator 14, which is connected to

the connecting shaft 13 of the motor 11 , rotary power of the motor 11 being transmitted to

the generator; an automatic voltage regulator 15, which is connected to the generator 14,

receives a current from the generator 14, and generates a stable output voltage irrespective

of variations of an input voltage or a load capacity; an uninterruptible power supply (UPS) 16,

which is connected to the automatic voltage regulator 15, receives a current of a constant

"voltage, and provides a current of a constant voltage even when an electrical shutdown or a

voltage drop happens; a transformer 17, which is connected to the uninterruptible

power supply 16; and an acceleration, which is connected to the transformer 17 and the

motor 11 and increases rotary power of the motor 11 by using a current supplied from the transformer 17.

Therefore, when power is supplied to the motor 11 from a car battery or an external

power source in a short period of time, the connecting shaft 13 of the motor 11 is rotated to

drive the generator 14, so that power is generated by the generator 14. Then, the

generated power is supplied to the automatic voltage regulator 15. If a stable output

voltage through the automatic voltage regulator 15 is input to the UPS 16, power can be

continuously output from the UPS 16 even when an instant electrical shutdown happens in

the output power boost device 10. The power continuously and stably supplied by the UPS 16 to the transformer 17 increases rotary speed of the motor 11 when it is supplied to the

motor 11 by the acceleration 18. Finally, the output power of the power transmission shaft

12 from the motor 11 is increased. Therefore, efficiency of a drive unit connected to the

output power boost device can be maximized. Technical Solution

A stable voltage output from an automatic voltage regulator 15 is input to an

uninterrupted power supply (UPS) 16. Operation methods of the UPS can be classified into

an "on-line" type shown in FIG. 3 and an "off-line" type shown in FIG. 4. A difference

between them is as follows.

As shown in FIG. 3, the on-line type is an inverter-driven type. According to the

on-line type, the voltage from the generator 14 and the automatic voltage regulator 115 is

converted into a direct current (DC) voltage and then an alternating current (AC)

voltage, so that a constant stable power can be supplied to load devices without a shutdown

time. Therefore, an output power has a sinusoidal waveform of a constant voltage and a

constant frequency. Of course, a back-up time can be prolonged depending on a user's

selection.

As shown in FIG. 4, according to the off-line type, the power from the generator 14

and the automatic voltage regulator 15 is directly output to loads in a normal condition, but,

only in a shutdown condition, the inverter is operated to compensate for a shutdown time.

The off-line type is usually adapted to a small capacity of UPS (e.g., below 1KVA). Also, it

has a short back-up time and outputs a sine or rectangular wave.

The power input to the UPS is input to a transformer 17 and then supplied to a motor

11 by an acceleration unit 18, so that the output power of the motor 11 can be improved. However an output power boost device according the present can be operated to

drive the motor 11 by using a starting motor as described above, also power of a battery 3

can be directly supplied to the transformer 17 when starting up and then transmitted to the

motor 11 through the acceleration 18.

On the other hand, when an output power boost device according to the present

invention is used for a boiler, the motor 11 can be driven by using any power supply

embedded in side walls near the boiler. In this case, if the motor corresponds to a direct

current (DC) motor, the power to be supplied can be converted into a direct current and then

supplied.

Advantageous Effects

In the output power boost device according to the present invention, if power starts to

be supplied to the motor 11 by a car battery or an external power supply in a short time, the

connecting shaft of the motor starts to rotate and the generator starts to be driven.

Subsequently, power is generated by the generator 14 and then supplied to an automatic

voltage regulator 15. If a stable output voltage through the automatic voltage regulator 15

is input to the UPS 16, the UPS 16 continuously outputs power even when a temporary

shutdown happens in an output power boost device 10. The power stably and continuously

supplied to the transformer 17 by the UPS 16 is made to increase rotary speed of the motor

11 when it is supplied to the motor 11 through the acceleration 18. Therefore, output power

of the power transmission shaft 12 driven by the motor 11 can be increased, so that efficiency of a drive unit connected to the output power boost device according to the

present invention can be maximized. Best Mode

An uninterruptible power supply (UPS) 16 is a system which automatically restarts to

supply power in an instant when an electrical shutdown happens. The UPS 16 is very

necessary when an electrical shutdown happens due to an accident in an electrical power

company, an amount of power consumption during a hot summer, natural disasters caused

by thunder or a heavy pouring, or an unstable power supply in an old building.

The UPS 16 can prevent data losses in a computer or operation errors in a control

device even when an electrical shutdown happens.

The output power boost device 10 according to the present invention comprises the

UPS 16, by which constant power can be continuously supplied to a transformer 17 and a

acceleration 18 which will be described below even when operation of the motor 11 is

interrupted so that power can not be supplied from the generator 14 during a predetermiried

period of time.

The UPS 16 is connected to a transformer 17. The transformer is to receive an

unstable alternating current and then constantly provide a quality of direct current with load

devices by adopting a high frequency variable control method.

The above transformer 17 and the motor 11 are connected to the acceleration 8 in

order to increase rotary power of the motor 11 by supplying the power from the transformer

17 to the motor 11

On the other hand, the transformer 17 may comprise an inverter for converting a

direct current into an alternating current or a diode for converting an alternating current into a direct current. The output power boost device according to the present invention can be installed in

a car transmission 4. When a starting switch 1 is turned on by using a car key, a switch 2

of a power ignition unit is turned on. Then, the power from a battery 3 installed in a car is

supplied to a starting motor to rotate a fly wheel, so that a power transmission shaft 12 of a

transmission 4 and a motor 11 connected to the transmission 4 can be rotated.

If the motor 11 is driven by such a starting operation, the generator 14 also starts to

be driven by the connecting shaft 13 so that power can be generated. The generated

power is input to the automatic voltage regulator 15, and then a stable voltage is output.

In the output power boost device according to the present invention, the amount of

power supplied to the motor 11 is increased when the acceleration 18 is stepped on, so that

rotary power of the motor 11 is increased. Subsequently, the amount of power generated

by the generator 14 as well as the rotary power of the power transmission shaft 12 is

increased simultaneously, so that a sufficient amount of power can be supplied to the UPS

16.

Therefore, since constant power can be supplied from the UPS 16 even when an

electrical shutdown happens during a predetermined period of time after power is supplied to

the motor 11 or the transformer 17 from the UPS 16, the output power of the motor 11 can

be continuously boosted. Therefore, drive efficiency of a car can be improved.

Mode for Invention

The present invention will now be described more fully with reference to the

accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 is a schematic diagram showing a state that an output power boost device

according to the present invention is installed in a car transmission, and FIG. 2 is a

schematic circuit diagram of FIG. 1. The output power boost device according to the

present invention comprises the motor 11 for driving the transmission 4 of a car.

The motor comprises a connecting shaft 13 in one side and a power transmission

shaft 12 in the other side. The power transmission shaft 12 is combined with the

transmission 4.

If the starting switch 1 is turned on by using a car key, the switch 2 of the power

conversion unit is turned on. Subsequently, the motor 11 starts to supply power from the

battery 3 installed in a car to a starting motor (not shown in the drawings). Then, a fly

wheel is rotated by the starting motor, and then the motor 11 is rotated.

A connecting shaft 13 of the motor 11 is connected to the generator 14, which is

operated in relation with the motor 11 so as to generate electricity when the motor 11 is

driven. The generator 4 is connected fo an automatic voltage regulator 15, so that stable

output power can be generated irrespective of variations of an input voltage or a load

capacity when the electricity generated by the generator 14 is input. As roughly described above, the automatic voltage regulator 15 is to provide a quality

of constant voltage source with load devices. For this purpose, when a voltage is not within

an allowance due to an unstable commercial power source or an instantaneous transient

phenomenon in a load device, the automatic voltage regulator 15 detects this by using a

digital integrated circuit and controls a TAB of the transformer by using a non-contact

semiconductor (i.e., Traic).

The automatic voltage regulator 15 is connected to an UPS 16, which receives a

current of a constant voltage from the automatic voltage regulator 15 and provides a current

of a constant voltage even when an electrical shutdown or a voltage drop happens.
