Induction oven generator

The monitoring of the internal intermediate circuit indicates undervoltage.
The seven-segment display of the inductor indicates '5'.

Remedy

The intermediate circuit is rectified directly by the AC supply. In the event of a fault in the AC supply (e.g. flicker) or a phase failure, the intermediate circuit will fail.
