2. 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]

3. 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.

4. Synchronverter - Wikipedia

   en.wikipedia.org/wiki/Synchronverter

   A synchronous generator’s rotating mass acts as a bank of kinetic energy for the grid to counteract changes in frequency – it can either provide or absorb power from the grid – caused by an imbalance of electric power supply and demand – in the form of kinetic energy by speeding up or slowing down.

6. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   Doubly fed induction generator (DFIG), a generating principle widely used in wind turbines. It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings. It is possible to avoid the multiphase slip ring assembly, but there are problems with efficiency, cost ...

   The YM2612, a.k.a. OPN2, is a sound chip developed by Yamaha.It is a member of Yamaha's OPN family of FM synthesis chips, and is derived from the YM2203. [1]The YM2612 is a six-channel FM synthesizer used in several game and computer systems, most notably in Sega's Mega Drive/Genesis video game console [2] as well as Fujitsu's FM Towns computer series.
