System higher for tolerance, such as power supply system can sense rear end system after the two-stage treatment of front
The residual voltage of system can meet its demand, i.e., the residual voltage will not cause to damage to back-end system, therefore prime transient state is only needed to handle mould
Block and steady-state filtering module can protect back-end system.But system lower for tolerance, such as communication system are sensitive
Degree is very high, after the two-stage treatment of front end, can sense the residual voltage of back-end system, still can cause to it different degrees of
Damage, it is therefore desirable to design rear class transient state processing module and cooperate jointly with prime transient state processing module, to protect system.
The foregoing is merely illustrative of the preferred embodiments of the present invention, the protection scope being not intended to limit the invention, any
Those skilled in the art within the spirit and principles in the present invention made by any modifications, equivalent replacements, and improvements etc.,
It should all be included in the protection scope of the present invention.
