摘要： Commonly, a transient protection filter circuit is integrated between power sources and the circuits that follow to suppress voltage transients. Pre-existing transient protection filters are implemented such that when a transient is detected, transistors in the path become linear regulators. Instead, this invention uses bridge resistors to form a voltage divider to dissipate the extra power. The novelty of this invention is that it protects the load not by dissipating the extra power in front of the load as other transient protection filter circuits do, but by providing energy from the transient to the load through a resistor. This implementation solves the problem of thermal runaway that is commonly caused when transient \roltages are filtered by dissipating power within r the transistors in the path of the transient and the electric circuits after the transistors.
摘要翻译：通常，瞬态保护滤波器电路集成在电源和随后的电路之间以抑制电压瞬变。实现了现有的瞬态保护滤波器，使得当检测到瞬态时，路径中的晶体管变为线性稳压器。相反，本发明使用桥式电阻器来形成分压器以耗散额外功率。本发明的新颖之处在于，其它瞬态保护滤波器电路不是通过消耗负载前面的额外功率来保护负载，而是通过电阻将瞬态能量提供给负载。该实现解决了当通过在晶体管之后的瞬态路径和电路中的晶体管内消耗功率来过滤瞬态电压时通常引起的热失控的问题。
