This overvoltage protection or crowbar protection circuit is used where we need protection against high voltage surge. The circuit has a few components, it is very easy to build and will protect your ...

An additional circuit connected between the load side of a ground-fault circuit interrupter (GFCI) and ground provides overvoltage protection against long-duration overvoltages, e.g., where the line ...

There are some design complications encountered in applications that use single-supply circuitry to process an ac input signal. One drawback is that the signal often can’t be attenuated and ...
