| Top > Solution > Abnormal operation of overvoltage protection |
| If designed properly, if the overload condition continues for a certain period of time, oscillation will stop and restart repeatedly. As shown in the photo below, even in an overload condition, the auxiliary winding voltage will not rise to the overvoltage detection voltage. |
 |
| However, if there is a problem with the regulation of the auxiliary winding,
the overvoltage protection will abnormal operation under overload. |
