Transient Energy Suppression in Design of Intrinsic Safe Power Source

This paper introduces the test of the current protection value of the intercepting power source and the production process of transient energy, analyzes the factors of transient energy production, proposes two methods of transient energy suppression in design of intrinsic safe power source, which solves the problem of failure of spark ignition test and transient energy test in the design process of intrinsic power supply, and one of the methods is verified.
