Resonant high-frequency inverters using static induction transistors

The authors describe voltage-fed full bridge series resonant inverters using static induction transistors (SITs) which operate efficiently in the frequency range of 100 approximately 1000 kHz. The trial inverters are applied to 100 kHz and/or 400 kHz high power induction heating and melting power supplies. In addition, a quasi-resonant inverter suitable for radio-frequency applications is produced to diminish switching losses operating at 1 MHz. Both types of inverter are found to work safely with sufficiently high efficiency in feeding high output power.<
