With the addition of a power converter, renewable energy systems must be extracted more efficiently. Renewable energy sources are obviously used to generate clean energy. This clean energy cannot be used directly on load due to fluctuating conditions; to address this, a modified AC to DC converter with a ripple-free output is introduced. This AC to DC converter is made up of a rectifier and an LC filter that run independently in their half cycles and share an input inductor. This AC to DC converter is both cheap and effective. The input current is precisely phase-locked to the source voltage, yielding a high input power factor. In addition, the source current voltage ripple was reduced to less than 5V. It was discovered that the converter with Capacitor has significantly lower ripple and far superior voltage regulation than the converter without Capacitor. The simulation was carried out in MATLAB/SIMULINK, and the experimental parameters were determined using a standard prototype.
