2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   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]

3. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.

4. NEMA connector - Wikipedia

   en.wikipedia.org/wiki/NEMA_connector

   The NEMA TT-30 (TT stands for Travel Trailer) connector is a 120 V 30 A recreational vehicle standard (hot-neutral-ground), also known as RV 30. The TT-30R receptacle is commonly available in nearly all RV parks in the United States and Canada, and all but the largest RVs manufactured since the 1970s use this plug to connect to power feeds.

5. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

6. AS/NZS 3112 - Wikipedia

   en.wikipedia.org/wiki/AS/NZS_3112

   A variant of the Australian standard 10 amperes plug has a socket on the back to allow connection of a second appliance to the same outlet. This type of plug is known officially as a "socket adapter plug" but is referred to colloquially, in Australia, as a "piggy-back plug", or in New Zealand, as a "tap-on" plug and is shown below to the right.

7. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   In a so-called balanced power system, sometimes called "technical power", an isolation transformer with a center tap is used to create a separate supply with conductors at balanced voltages with respect to ground.
