context_page_description: Resonant inverters are electrical inverters based on resonant current oscillation. In series resonant inverters the resonating components and switching device are placed in series with the load to form an underdamped circuit. The current through the switching devices fall to zero due to the natural characteristics of the circuit. If the switching element is a thyristor, it is said to be self-commutated.
context_section_description: 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 resonating components is small.
