Dc-dc q-zsc with buck-boost converter gain
In this paper, a DC-DC buck-boost converter (BBC) based on the quasi Z-source converter (q-ZSC) topology is proposed. The converter is classified as buck-boost because their gains are the same. It is also classified as an impedance source converter (ISC) because it is based on q-ZSC topology. These...

| Summary: | In this paper, a DC-DC buck-boost converter (BBC) based on the quasi Z-source converter (q-ZSC) topology is proposed. The converter is classified as buck-boost because their gains are the same. It is also classified as an impedance source converter (ISC) because it is based on q-ZSC topology. These shared properties of the buck-boost and q-ZSC gives it advantages over each of these two converters. The gain curve gives it advantages over a corresponding regular q-ZSC because for a given duty ratio, it has a higher gain, while it's topology edge it over a corresponding BBC thus permitting higher frequency operation, elimination of dead time, shoot-through effects etc. MATLAB/SIMULINK was used to compare its performance and corresponding BBC for a buck mode and boost mode operation. The simulation results show that their responses are very much similar. |
