2. 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 ...

3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Utility frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.

4. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power Converters can include simpler tools such as transformer or more complex like a resonant converter .

5. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances ...
