Patent ID: 8179655

Claim:
A surge protected system, comprising: first and a second primary over-voltage protection circuits; first and a second common mode inductors; first and a second coupled inductors, said coupled inductors comprising coils that are magnetically coupled to each other; first and a second secondary over-voltage protection circuits; and a signal conditioning circuit; wherein said first secondary over-voltage protection circuit is disposed at a first side of said signal conditioning circuit, and said second secondary over-voltage protection circuit is disposed at an opposite side of said signal conditioning circuit; wherein said first primary over-voltage protection circuit is disposed at a first side of said signal conditioning circuit, and said second primary over-voltage protection circuit is disposed at an opposite side of said signal conditioning circuit; wherein said first common mode inductor is disposed at a first side of said signal conditioning circuit, and said second common mode inductor is disposed at an opposite side of said signal conditioning circuit; and wherein said first coupled inductor is disposed at a first side of said signal conditioning circuit, and said second coupled inductor is disposed at an opposite side of said signal conditioning circuit.
