What component converts 220 volts AC to 12 volts DC so your PC can use it?

power supply
The power supply converts the alternating current (AC) line from your home to the direct current (DC) needed by the personal computer.

Can you use a higher voltage transformer?

Yes, as long as you get one of our voltage transformers/converters. Consider buying a higher wattage transformer then the wattage rating of your appliance.

What will happen to the load current if the source voltage suddenly increases?

The current is directly proportional to the voltage and inversely proportional to the resistance. Any alteration in the voltage will result in the same alteration of the current. So doubling or tripling the voltage will cause the current to be doubled or tripled.

What happens if too much high voltage is applied to a transformer?

As the higher voltage gives a higher current (Ohms Law). the current on the primary does increase, so the power (voltage * current) will be much higher, and the transformer will overheat and burn out.

How to get 220V AC from 12V DC source?

The article explains a very simple method of acquiring 220V AC from a 12v DC source. The idea utilizes inductor/oscillator based boost topology with the help of the IC 555. We are quite familiar about inverters which convert a DC potential to higher AC potentials at mains levels.

How to convert DC potential to AC potential at Mains levels?

We are quite familiar about inverters which convert a DC potential to higher AC potentials at mains levels. However these units involve complex and expensive configurations for acquiring the required outputs. A much simpler approach of achieving the above results is by employing a oscillator mosfet boost converter circuit.

What size MOSFET wire do I need for a 220V motor?

For example if the required output is 220V, the 47K preset may be adjusted such that the220V mark never exceeds, irrespective of the coil back emf rate or the input voltage fluctuations. The mosfet can be any 30V, 50 amp type, for example a NTD4302 may be used. The coil wire should be thick enough to hold up to 30 or more amps.

Can a DC converter be used on a home appliance?

Although this is not part of any professional dc ac converter it can be used quite effective on some home appliances. Be aware that the output signal is square and not sine wave.
