For generic power conversion (e.g., heat to electric energy), see energy transformation.
For national power supplies, see Mains electricity by country.
In electrical engineering, power engineering and the electric power industry, power conversion is converting electric energy from one form to another, converting between AC and DC, or just changing the voltage or frequency, or some combination of these. A power converter is an electrical or electro-mechanical device for converting electrical energy. This could be as simple as a transformer to change the voltage of AC power, but also includes far more complex systems. The term can also refer to a class of electrical machinery that is used to convert one frequency of alternating current into another frequency.
Power conversion systems often incorporate redundancy and voltage regulation.
One way of classifying power conversion systems is according to whether the input and output are alternating current (AC) or direct current (DC), thus:
There are also devices and methods to convert between power systems designed for single and three-phase operation.
The standard power frequency varies from country to country, and sometimes within a country. In North America and northern South America it is usually 60 hertz (Hz), but in many other parts of the world, is usually 50 Hz. Aircraft often use 400 Hz power, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the airplane while it is on the ground.
Certain specialized circuits, such as the flyback transformer for a CRT, can also be considered power converters.
Consumer electronics usually include an AC adapter (a type of power supply) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips. Consumer voltage converters (also known as "travel converters") are used when travelling between countries that use ~120 V vs. ~240 V AC mains power. (There are also consumer "adapters" which merely form an electrical connection between two differently shaped AC power plugs and sockets, but these change neither voltage nor frequency.)

With havin so much written content do you ever run into
any issues of plagorism or copyright infringement? My website has a lot of unique content I've either created myself or outsourced but it seems a lot of it is popping it up
all over the web without my authorization.
Do you know any solutions to help protect against content from being ripped off?
I'd really appreciate it.

I am really enjoying the theme/design of your site.
Do you ever run into any web browser compatibility problems?
A couple of my blog audience have complained about my website not working
correctly in Explorer but looks great in Opera. Do you have any tips to help fix this issue?

I don't know whether it's just me or if everyone else experiencing issues with your website.
It looks like some of the text within your posts
are running off the screen. Can someone else please
provide feedback and let me know if this is happening to them too?
This may be a problem with my internet browser because I've had this happen before.
