Malfunction of the overvoltage protection function during overload.

If properly designed, the auxiliary winding voltage will not rise to the overvoltage detection voltage
even in overload conditions, as shown in the photo below.
If the overload condition continues for a specified period of time,
oscillation will stop and restart will be repeated.
