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.[1] 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.how to install an air conditioner wall unit Certain specialized circuits, such as the flyback transformer for a CRT, can also be considered power converters.replacing rv ac unit 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. different types of flexible ac transmission system

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.)Our mission is to provide power supply solutions that meet the technical, budgetary and time frame demands of your applications.

New generation AC-DC converters reduce power consumption and increase efficiency, essential for powering the majority of mains equipment.  When combined together, ST power factor correctors, PWM controllers and offline converters significantly lower system power consumption to outperform the most demanding energy-saving regulations, such as 80 PLUS® Initiative, ErP Lot 6, Energy Star, and many others. VIPer0P zero-power offline high-voltage converter Introducing the VIPer0P high-voltage converter with jittered fixed-frequency current-mode PWM control for simplified EMI compliance and zero-power mode (ZPM) with an astounding < 4 mW (at 230 VAC) consumption.

VIPer0P can enter and exit ZPM when the low voltage input/output pins (OFF or ON) are pulled to ground so a small and inexpensive safety extreme low voltage (SELV) switch can replace the bulky mains switch. The VIPer0P embeds a set of protections – including over-current protection (OCP), VCC clamp, maximum duty cycle and flux runaway – to enable a more robust and safer SMPS design. The VIPer0p is ideal for all SMPS up to 7 W having a wide input voltage range including: Home appliances compliant with EuP Lot6 energy regulation Industrial equipment or digital consumer goods Explore all the key benefits of the VIPer0P high-voltage converter with unique zero-power mode with the STEVAL-ISA174V1 non-isolated, flyback 6 W SMPS evaluation board. 230 V - 50 Hz 115 - 60 Hz Wide Range - 50 HzWilmore Electronics Co., Inc.
