Resonant inverter

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.

Applications

Electronic ballast for the Fluorescent Lamp
Current Resonant Inverter circuit for the CCFL lighting

This type of inverter produces an approximately sinusoidal waveform at a high output frequency, ranging from 20kHz to 100kHz, 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 are small.
