This paper focuses on the analysis of Electromagnetic Interference Problem associated with the resonant converters because it affects their Electro Magnetic Compatibility (EMC). The principle of Electromagnetic Compatibility (EMC) is to allow a correct and optimum functioning of any electrical or electronic devices in the presence of each other. In other words, it is the right of electrical/electronic equipment to co-exist in an electromagnetic environment without disturbing each other.
