No, a transformer does not change AC to DC. For this purpose there is a device known as a rectifier, and to transform it back to AC from DC you'll need an inverter.

Transformers are only useful with AC due to the alternating waveform which induces a voltage in the secondary winding (when it is connected to a load).

A transformer is an AC supply device. You can use a transformer to build a DC supply, but the basic device is AC. There are power adapters on the market that produce DC. Rest assured that they contain multiple components, not just a transformer, in order to do that.

The transformers secondary voltage outputs vary between 7500 to 15000 volts. The voltage is governed by the length of the neon tubing.

What type of electrical equipment cannot convert AC into DC?

A transformer cannot convert AC into DC.


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 24volts to 12 volts?

If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v 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.


How do you make ac into DC in a ac transformer?

You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater


Why do you obtain more dc voltage than ac voltage in power supply design by using transformer?

You don't. Transformers only work with AC voltage. Their input will be an AC waveform, and their output will be an AC waveform. Other electronics are used to convert the stepped down AC waveform from the transformer to DC.


How do you convert a DC to AC inverter into a grid tie inverter?

A grid DC tie is where AC is converted into DC, which is then converted to AC again on the other side. If you have a DC to AC transformer setup, you'd need to add a second one going the "other" way for a full DC tie station.


What will happen when a single diode is connected to a transformer with ac signal?

it convert ac signal into dc signal But it will give only half-wave rectification.


If DC is applied to the primary of a transformer is there any current in the secondary and if there is then whether ac or DC?

first, understand that a transformer is an AC DEVICE. it wont work on dc...


How are is a transformer and a rectifier different?

A transformer changes the VOLTAGE of AC current (AC to AC). A rectifier changes AC to DC.


Why isn't there a DC transfromer?

An AC transformer works by changing the magnetic field going through a coil. The change is unavailable in the case of DC. It is possible to convert DC to AC (with an inverter) and then change the AC voltage to another value and rectify it to get DC at a different voltage.


Can transformer operate on triangular wave DC?

If its a triangular wave, its not DC, its AC, its just not sinusoidal. Can a transformer operate on triangular AC? Yes, but not as efficiently as on sinusoidal AC.
