“…In order to perform the theoretical analysis of the integrated boost-flyback converters and access their characteristics, the Boost-flyback with Series Output (Table II) has been chosen to demonstrate the principle of operation for the integrated topologies. For information on the principle of operation of the Boost-flyback with Parallel Output and Boost-flyback with Cascade Output (Table II), see [37].…”

This paper presents a new integration concept to generate high voltage step-up non-isolated DC/DC converters with the aid of coupled-inductors. The integration concept relies on the separation of the converter circuit into two or three parts named input, middle and output sections. Hence, any basic converter can partially or fully share one of its sections with another basic converter since both circuits comply with the integration rules. The merged converters become an integrated topology with fewer components. According to this paper, for the input section parallel integration, the circuits remaining output sections can be associated in three different ways, in a series, parallel or cascaded connection. These output sections associations allow for a merged topology to enhance their voltage gain that becomes the sum of the voltage gains of the former topologies alone. An example of integration of the boost and flyback converter is provided to illustrate the theory. The resulting integrated topologies are theoretically and experimentally evaluated. The results prove that the integration methodology is an effective way to obtain high voltage conversion ratio circuits and that the derived topologies are highly efficient due to their low converter series resistances.

“…For instance, a three-level boost converter can double the voltage gain and halve the voltage stress of the power device compared with conventional boost converter topology. Regrettably the number of switches is twice [14][15].…”

“…Hence, for a very high step-up voltage, a great amount of voltage multiplier cells are necessary. Additionally to the cost and conduction losses, some topologies that employ such voltage multiplier bridge also have an additional shortcoming that is the periodical shortening of part of the capacitors by the switch [14][15].…”

This paper proposes an analysis of a high step-up DC/DC converter named Integrated Quadratic-Boost-Zeta converter. It is based on the combination of two well-known DC/DC converter circuits, the Isolated Zeta converter and the Quadratic-Boost converter. The aim of this paper is to analyze the voltage static gain, the voltage and current stresses on the components of the converter as well as its main features. Additionally, the derivation for three different alternative topologies is presented and their principles of operation, features and limitations are discussed. Experimental results obtained from a laboratory prototype rated at 250W and 100 kHz prove the feasibility and reliability of the proposed converters.
