| titleOfInvention | PoE port overvoltage integrated protection circuit and its implementation |
| abstract | The invention discloses a kind of Power over Ethernet (PoE) port overvoltage integrated protection circuit and its implementation, this circuit comprises two-stage protection circuit, wherein: first order protection circuit adopts three pole gas discharge tubes, for realizing releasing over the ground of thunder-strike current; Second level protection circuit adopts clamper type over-voltage protector, for realizing first order protection residual voltage and electrostatic defending; Between described first order protection circuit and second level protection circuit, adopt resistance and common mode inductance combinational circuit, to coordinate the operating characteristics between described two-stage protection circuit and device, reach the effect of decoupling between first order protection circuit and second level protection circuit.Adopt the present invention, the balance of protection circuit can be improved, reduce common mode overvoltage and be converted into the superpotential amplitude of differential mode and energy, to improve protection effect. |
