Based on figure attached, I would like to design an overvoltage protection circuit at the selected red rectangular area.
The voltage supply for the circuit is 230V with 50Hz. The protection circuit should somehow block the voltage when the power supply voltage reach 110% of the nominal voltage. When the voltage return to the nominal voltage, the circuit should allow the current to flow again. Any suggestion to achieve this requirements?? Thank you.
