Design and Development of Modified LLC Resonant Converter

The study aims to address the issue of switching losses that occur during the charging of DC appliances. Switching losses occur when electrical devices switch on and off, causing energy to be lost in the form of heat. The study proposes a solution by replacing the existing double-sided LLC resonant converter with a modified LLC resonant converter. The modified LLC resonant converter uses fewer switches to convert DC to AC and produce a stable high output in an electrical circuit. This converter is more efficient than the double-sided LLC resonant converter, which produces an unstable output with low efficiency, leading to switching losses. By replacing the double-sided LLC resonant converter with a modified LLC resonant converter, the study aims to reduce the switching losses and increase the compactness of the system. The modification is expected to result in a more efficient and stable output, reducing switching losses and improving the overall performance of the system. Overall, the study proposes a technical solution to the problem of switching losses during the charging of DC appliances by replacing the double-sided LLC resonant converter with a modified LLC resonant converter. This solution is expected to enhance the effectiveness and stability of the system and increase its compactness, leading to more efficient and reliable system.
