Multi-input Power Converter for Renewable Energy System with Droop Current Sharing Technique

This paper proposed the design and simulation of a multi-input (3inputs) paralleled DC-DC Boost Converter with single output. By paralleling modules of power converter, it offers a lot of advantages over a single, centralized and high power supply converter but the drawback is, if one of the inputs...
