2. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC).

3. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   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, due to the conversion from DC to AC rather than the voltage change. The output frequency and waveform of an inverter may not accurately replicate that supplied by mains electricity ...

4. Energy conversion efficiency - Wikipedia

   en.wikipedia.org/wiki/Energy_conversion_efficiency

   Efficiency of power plants, world total, 2008. Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat.

5. 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 ...

6. 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.

7. Category:Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Category:Electric_power...

   Articles in this category are about converting electric energy from one impedance, phase or frequency (including direct current) to another.But the energy form remain in the same domain and the focus is on energy conversion – not signal conversion or measurement (like Current-to-voltage converter or Voltage-to-current converter).
