How does DC converts into ac?

Answer 1

A rectifier converts from AC to DC power by blocking one half of the AC current. A full-wave bridge rectifier is actually 4 rectifiers combined in such a way that it reverses the blocked half of the power, allowing it to flow through.

A standard power supply consists of a transformer (for voltage changes), a rectifier, and additional components for cleaner power (e.g., filters to smooth out the waves of AC power, voltage regulator, etc.).

Answer 2

By using a rectifier.

A transformer cannot by itself be used to convert AC to DC, and one cannot use a transformer with DC (say a battery). A transformer requires AC so that it can induce current into the secondary windings, which then steps down (or steps up) the output AC voltage. The output AC can then be rectified into DC using diodes (or a bridge rectifier).

Answer 3

An AC power supply device can convert DC power to AC power source. The transformer will control the output voltage to the desired level that equipment can tolerate. The answer above won't work because Transformers don't work on DC. Some ways that will work are :- # A rotary converter (aka motor-generator set). This is just a DC motor and an AC generator mounted on the same shaft. Heavy, and the output voltage and frequency both vary a lot with variations in the input voltage. # An electronic unit consisting of an oscillator which generates a sine wave at 50Hz or 60Hz (as required) followed by a power amplifier. This then feeds a transformer to give the required AC output voltage. This unit is often called an Inverter. If you just need a few hundred watts AC from 12V DC then Inverters are readily available.
To convert DC to AC you need an inverter or a motor-generator set.

Answer 4

By way of rectifiers - which are diodes (allow current to flow in one direction only), coupled with other electronics used to smooth the AC wave. A simple design includes a rectifier, a power transistor, a zener diode in series with a small resistor to help keep the power transistor base voltage constant, and a capacitor on the output of the power transistor to further smooth the output from the transistor.

Answer 5

If you are talking about electrical current, yes you can do it. It is done with a "transformer" (not the ones on telephone poles) These are found on electronics chargers in the USA regions (and some others) where AC current is used. But if you tamper with these be VERY careful not to touch anything inside of it, as there are capacitors in there that can nab you with enough to kill. They can still be charged even after being unplugged (not permanantly). Also make sure it doesnt short circuit. It will smoke and eventually will catch fire

Answer 6

You put it through rectifiers or diodes.

Answer 7

Rectifer, it could be single-phase or three-phase

Answer 8

Convert DC to AC through MOSFET,THYRISTOR,IGBT that's like Inverter Circuit.It can be use UPS,INverter

Answer 9

If you don't mind variable voltage DC, a simple four-diode rectifier is sufficient.
