A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]
APC was founded in 1981 by three MIT Lincoln Lab electronic power engineers. Originally, the engineers focused on solar power research and development. [2] When government funding for their research ended, APC shifted its focus to power protection by introducing its first UPS in 1984.
An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation ( CIG ), include the variable renewable energy generators (wind, solar) and battery storage power stations ...
A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC.

Push-pull converter (+12V → ±18V; 50W) as potted module. ① transformer; ② and ③ electrolytic capacitors vertical and horizontal mounted; ④ discrete circuit board in through-hole technology. A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC power supply.
Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as ...
