There is no way to store AC voltages as such. A battery is a storage device so AC is converted to DC for storage. When AC fails the stored DC voltage is then changed back to AC through a device called an inverter. The inverter outputs a square waveform instead of a sinusoid waveform but most loads, such as a computer power supply that is connected to the UPS, can not tell the difference.

How a ballast resistor convert DC into ac?
A resistor, by itself, can not convert DC into AC.
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
How do you convert ac generator to dc generator?
Such conversions are often inefficient and/or expensive. It requires an external power supply or battery charger to convert AC into DC.
How a ballast resistor convert DC into ac?
A resistor, by itself, can not convert DC into AC.
How ac change to DC?
by the use of inverter we can convert ac to dc.
What type of electrical equipment cannot convert AC into DC?
A transformer cannot convert AC into DC.
How you convert DC TO ac?
we can convert a dc supply to an ac supply using inverters. Its a common operation which we observe in our daily lives dc can be converted to Ac using an undulator.
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
How do you conyert AC to DC?
You rectify AC voltage through a diode bridge to convert it to DC.
What component converts AC into clean DC power?
By using rectification we can convert the AC into DC....
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Does electrical transformer use a DC or AC source?

Is bulb contains a rectifier to convert ac to dc?
No. A bulb can run a AC just a easily as DC.
How do you build a dc to dc converter?
A DC to DC converter is basically a type of switching power supply. The switcher converts the input DC to AC. A transformer is used to convert the AC to the desired voltage. A rectifier, filter, and optional regulator is used to convert the AC back to DC.
Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
