3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Sine wave. A power inverter device that produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three-step) inverter designs, the manufacturers often use the phrase pure sine wave inverter.

4. Inverter-based resource - Wikipedia

   en.wikipedia.org/wiki/Inverter-based_resource

   An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]

5. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   The energy lost during inversion is for the most part converted into heat. Consequently, for an inverter to output its rated power it must have a power input that exceeds its output. For example, a 5000 W inverter operating at full power at 95% efficiency requires an input of 5,263 W (rated power divided by efficiency).

6. Alternating current - Wikipedia

   en.wikipedia.org/wiki/Alternating_current

   The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa (the full period is called a cycle). "Alternating current" most commonly refers to power distribution, but a wide range of other applications are technically ...

7. Vibration-powered generator - Wikipedia

   en.wikipedia.org/wiki/Vibration-powered_generator

   According to the team that created the device, the vibrations from the heart muscles would be enough to allow the generator to power a pacemaker. [2] This would eliminate the need to replace the batteries surgically. In 2012 a group at Northwestern University developed a vibration-powered generator out of polymer in the form of a spring.
