2. 48-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/48-volt_electrical_system

   A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

3. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   Thus, devices usually can be used on either any voltage from approx. 100 to 120 V, or any voltage from approx. 210 to 240 V. In such cases, voltage converters need only be specified to convert any voltage within one range, to a voltage within the other, rather than separate converters being needed for all possible pairs of nominal voltages (110 ...

4. Boost converter - Wikipedia

   en.wikipedia.org/wiki/Boost_converter

   A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input to its output . It is a class of switched-mode power supply (SMPS) containing at least two semiconductors, a diode and a transistor , and at least one energy storage element: a capacitor , inductor , or the two in ...

5. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   24, 36, and 48 V DC, which are common standards for home energy systems. 200 to 400 V DC, when power is from photovoltaic solar panels. 300 to 450 V DC, when power is from electric vehicle battery packs in vehicle-to-grid systems. Hundreds of thousands of volts, where the inverter is part of a high-voltage direct current power transmission system.

6. Buck converter - Wikipedia

   en.wikipedia.org/wiki/Buck_converter

   A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...

7. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power. (There are also consumer "adapters" which merely form an electrical connection between two differently shaped AC power plugs and sockets , but these change neither voltage nor frequency.)
