Series intermediate frequency furnace
The series one-to-two intermediate frequency furnace adopts thyristor fully controlled rectifier bridge. In the series resonant power supply, the rectifier thyristor is always in a fully open working state under any circumstances, so it ensures the stable DC voltage output and does not reduce the power factor. And increase the harmonic content. When the power supply fails or alarms, the thyristor fully controlled rectifier bridge is equivalent to a solid-state control switch,
