摘要：
To investigate what an important role the shunt resistance branch circuit plays in overvoltage protection, this paper firstly analyzed the typical circuit with Kirchhoff's law. Then, by using Laplasse transform and inverse transform, the curves of voltage, current and power changing with time were obtained after the overvoltage occurs. After analyzing these curves, the essential role of RC protection playing was finally found, which can be seen as a temporary channel of circulation for overvoltage's prompt energy. In this channel, a large amount of energy will release in a short time, which played a very good effect on overvoltage protection.
