Example of Over-voltage Protection Circuit.
Generally, in constant-voltage power supply circuit, output voltage will become higher than the specied value
(over-voltage state) in case of any failures or PC board solderability defects. To minimize the damage caused by this
over-voltage, we recommend setting an over-voltage protection circuit.
In designing, the following conrmations are necessary in actual circuit.
1) How the over-voltage protection circuit operates and its effects.
2) Is there any malfunction due to ambient temperature change of each device or exogenous noises?
Over-voltage Protection Circuit Example
Example of Over-voltage Protection Circuit.
The thyristor will operate when it accept an over-voltage (VOUT) signal, then the fuse is melted and the input power is
cut off, then the operation of IC1 is stopped.
