A cost effective PC based Eddy Current Testing System is designed and developed to detect surface cracks in non-magnetic metals. The developed system is composed of Constant Current AC Source for excitation of the probe; and demodulation circuitry for acquisition of the signal from the crack. Eddy Current Testing Probe is also designed using the Analytical Approach. Surface cracks were successfully...
This paper presents a novel design of a wireless power transmission system which transfers an appreciable amount of electrical power wirelessly using low resonant frequency, with an excellent efficiency, and has a very low cost implementation. The designs of induction coils at both source and receiver sides are also presented in this paper. The mechanism for power transmission is through electro-magnetic...
