Abstract :
The authors describe voltage-fed full bridge series resonant inverters using static induction transistors (SITs) which operate efficiently in the frequency range of 100~1000 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
