Abstract :
This paper presents a new non-insulated quadratic three-level DC-DC boost converter. The quadratic feature is interesting for application where a wide voltage range is necessary. Since it is a current-source converter, its application in a fuel cell energy conversion system is interesting. Theoretical analysis for CCM of operation and experimental results are presented. A comparison between the two cascaded boost converter, the single switch quadratic boost converter and the proposed converter is made regarding commutated power. The efficiency of the proposed converter is higher than the others.
