Performance Improvement of Partially-Shaded PV Modules Connected DC Micro grid Systems

It intended to acquire SEPIC converters, which have been utilized in a variety of applications It has two major drawbacks, the first of which is that it places power semiconductor devices are subjected to high voltages, and secondly, the power switches must work very hard, resulting in low efficiency. Power semiconductor devices with a higher voltage rating should be used, especially for high voltage applications. When the voltage rating goes up, power MOSFETs tend to have a higher Rds(on) value. As a consequence of this, it results in a greater amount of conduction loss when the current level remains the same. Consequently, if the current is held constant, decreasing the voltage stress can improve efficiency. The dynamic performance is enhanced.
