| description | Abstract This paper deals with a family of two‐ and three‐windings coupled inductor‐based impedance source networks. They have been basically derived from the successful quasi‐Y‐source network (q‐YSN) by replacing one of its capacitors with a diode with different combinations of coupled inductors and called diode assisted impedance source networks (DA‐ISNs). The general three‐windings version, called diode‐assisted Y‐source network (DA‐YSN), as the origin of all other simplified versions, is thoroughly investigated from various points of view. From the voltage gain characteristics aspect, it offers a higher voltage gain with the same number of elements as the conventional q‐YSN. Lower magnetizing and input current ripples show the higher power density of DA‐YSN in comparison to q‐YSN. The effectively reduced voltage stress and the total value of capacitors, and a considerable decreased conversion loss of the magnetic element are the other attractive features of DA‐YSN. With the advantages of a low input current ripple and a high voltage gain, DA‐ISNs can be suitable choices for renewable energy and distributed power generation systems. Operating principle, circuit analysis, and parameters design guidelines for DA‐YSN are thoroughly investigated. Also, the small‐signal modelling, analysis and the controller design are presented in this paper. Finally, the theoretical properties of DA‐YSN are scrutinized by performing extensive experiments on a 200 W laboratory prototype. |
