New High-Gain Non-Inverting Buck-Boost Converter

This paper is presenting a new high-gain non-inverting buck-boost converter. The proposed converter has some distinct features such as high step up/down ability, low voltage and current stress on its switching devices. The voltage gain of the proposed converter is double of the traditional buck-boost converter and it is non-inverting. The three switches are operating synchronously. Although it has two inductors, the two inductors could be wounded on the same core due to similarity of the two inductors, and hence reduces the cost and size of the system. The overall efficiency of the system is promising due to the ability of selecting devices with low voltage drops. The steady state analysis of the system in both Continuous Conduction Mode (CCM) and discontinuous conduction mode (DCM) are presented in details. The system is simulated in MATLAB and results are discussed in detail through the paper. Experimental prototype is being build in the laboratory and hardware results will be presented in the final version.
