2. Recreational vehicle terms - Wikipedia

   en.wikipedia.org/wiki/Recreational_vehicle_terms

   Most operate on propane or AC (two-way), while some add 12 volts DC (three-way). Three-way (powered) RV refrigerators draw too much current to be powered by the house batteries, but may run on 12-volt DC power while the vehicle engine is running, a generator is running or the RV is connected to shore power. Newer models use 12 volts DC to ...

3. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   Switched-mode power supplies have become widespread in the early twenty-first century; they are smaller and lighter than the once-universal transformer converters, and are often designed to work from AC mains at any voltage between 100 and 250 V. Additionally, because they are typically rectified to operate at a DC voltage, they are minimally ...

5. Push–pull converter - Wikipedia

   en.wikipedia.org/wiki/Push–pull_converter

   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.

6. DC-to-DC converter - Wikipedia

   en.wikipedia.org/wiki/DC-to-DC_converter

   A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter . Power levels range from very low (small batteries) to very high (high-voltage power transmission).

7. Motor–generator - Wikipedia

   en.wikipedia.org/wiki/Motor–generator

   Large motor–generators were widely used to convert industrial amounts of power while smaller motor–generators (such as the one shown in the picture) were used to convert battery power to higher DC voltages. While a motor–generator set may consist of distinct motor and generator machines coupled together, a single unit dynamotor (for ...
