SURGE PROTECTION CIRCUIT AND SURGE PROTECTION METHOD
专利汇可以提供SURGE PROTECTION CIRCUIT AND SURGE PROTECTION METHOD专利检索，专利查询，专利分析的服务。并且The present invention provides a surge protection circuit and a surge protection method. The surge protection circuit may include: a first series-connected line formed by at least two TVSs connected in series (D3 and D4), wherein one end of the first series-connected line is connected to a positive terminal (XI), and the other end is connected to a negative terminal (X4); and at least one second series-connected line formed by at least one TSS (TH1, TH2), wherein one end of the second series-connected line is connected between the at least two TVSs in the first series-connected line, and the other end is grounded. The first series-connected line is connected in parallel to a protected circuit of a device; when a differential-mode surge voltage appears at the two ends of the first series-connected line, by using the first series-connected line, a voltage of a backend connection circuit is clamped to a first voltage value; and when a common-mode surge voltage appears at the two ends of the first series-connected line to the ground end, respectively, by using the first series-connected line and the second series-connected line, voltages to ground of the positive terminal and the negative terminal are reduced to a second voltage value. More effective surge protection can be provided according to this solution.，下面是SURGE PROTECTION CIRCUIT AND SURGE PROTECTION METHOD专利的具体信息内容。
