2. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   In North America and northern South America, it is usually 120 volts, 60 hertz (Hz), but in Europe, Asia, Africa, and many other parts of the world, it is usually 230 volts, 50 Hz. [2] Aircraft often use 400 Hz power internally, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the ...

3. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

   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.

5. DC connector - Wikipedia

   en.wikipedia.org/wiki/DC_connector

   In Australia, a T-configuration Clipsal socket is used for extra-low voltage DC power outlets, such as in stand-alone power systems (SAPS) or on boats, in order to prevent accidental connections of 12 V appliances into 240 V socket-outlets. [11] This connector is also used for temporary equipment in emergency vehicles.

6. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Waveform produced by a cigarette lighter 12 volt DC to 120 V AC 60 Hz inverter. The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a repeated voltage step sequence of zero, peak positive, zero, peak negative, and again zero.
