Small Signal Modeling of a DC-DC Type Double Boost Converter Integrated With SEPIC Converter Using State Space Averaging Approach

This study presents a detailed small signal analysis of a DC-DC type double boost converter integrated with SEPIC converter. The integrated converter has the features of the conventional boost and SEPIC converters, such as continuous input current, low input current ripple with extended step up capability. The converter consists of seven dynamic elements and hence it would be interesting to study the small-signal model of the converter. State-space averaging technique is used to derive the small signal model. The duty ratio control to output voltage transfer function is derived. A 50W prototype of the integrated double boost SEPIC converter is implemented using PIC 16F887 microcontroller, operating in continuous conduction mode. The measured results on the prototype verify the theoretical analysis.
