“…At present, the main DC-DC converter topology can be roughly divided into two types: non-isolated and isolated [13][14][15][16][17][18][19]. Several representative topologies of non-isolated DC converters include the buck circuit, the boost circuit, the buck-boost circuit, the cuk circuit, etc.…”

“…On the other hand, in reference [20] a novel N-stages flyback converter with parallel inputs and series outputs is presented. The main feature of this converter is that it considers the series connection of the secondary winding transformers instead of connecting in series the output capacitors of the individual stages, as in the interleaved ISOP topology.…”

“…This configuration allows to reduce the voltage peaks while the energy stored in the capacitor can be returned to the power supply, thus increasing the operating efficiency of the converter. In this work, a modified flyback converter based on the topology shown in reference [20] is presented. To reduce the voltage transient problems and increase the converter efficiency, active snubber networks are incorporated in every flyback converter transformer.…”

The research on DC-DC power converters has been a matter of interest for years since this type of converter can be used in a wide range of applications. The main research is focused on increasing the converter voltage gain while obtaining a good efficiency and reliability. Among the different DC-DC converters, the flyback topology is well-known and widely used. In this paper, a novel high efficiency modified step-up DC-DC flyback converter is presented. The converter is based on a N-stages flyback converter with parallel connected inputs and series-connected outputs. The use of a single main diode and output capacitor reduces the number of passive elements and allows for a more economical implementation compared with interleaved flyback topologies. High efficiency is obtained by including an active snubber circuit, which returns the energy stored in the leakage inductance of the flyback transformers back to the input power supply. A 4.7 kW laboratory prototype is implemented considering four flyback stages with an input voltage of 96 V and an output voltage of 590 V, obtaining an efficiency of 95%. The converter operates in discontinuous current mode then facilitating the output voltage controller design. Experimental results are presented and discussed.

Summary A new high gain DC‐DC converter based on single switch and three‐winding coupled inductor is presented in this paper. Existence of a three‐winding coupled inductor in suggested topology has led to lift voltage gain by low number of windings' turn ratio. As a result, the main advantage of the proposed converter is to produce a high voltage gain without great values of duty cycle. The passive clamped technology is used in the proposed converter. It causes better performance for proposed converter by recycling the leakage inductance energy as well as restricting voltage stress by reducing great voltage spikes. In this paper, performance analysis and mathematical equations of the proposed converter are explained. In addition, variations of voltage gain as a result of leakage inductance and voltage and current stresses of power devices are studied, too. Moreover, performance of the suggested converter and the previously presented high gain ones are compared with together. Lately, a 200‐W prototype is constructed, and the experimental results approve the effectiveness of the proposed converter.
