   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. Resonant inverter - Wikipedia

   en.wikipedia.org/wiki/Resonant_inverter

   This type of inverter produces an approximately sinusoidal waveform at a high output frequency, ranging from 20 kHz to 100 MHz, and is commonly used in relatively fixed output applications, for example, induction heating, sonar transmitters, fluorescent lighting, or ultrasonic generators. Due to the high switching frequency, the size of the ...
