Interleaved Double Dual Boost Converter for Renewable Energy System

Abstract

This paper presents an interleaved double dual boost converter (IDDB) used in renewable energy application where high voltage gain is required such as fuel cell or photovoltaic applications, etc. Two types of controllers are applied to this converter, 1) a controller based on Flatness properties for regulating the output voltage (outer loop); 2) a sliding mode controller for inductor current (inner loop). The variation of the input voltage is compensated by trajectory planning process. The validation of the proposed system is done through experimental results.
