In this paper, a new high efficiency, high step-up, non-isolated, interleaved DC-DC converter for renewable energy applications is presented. In the suggested topology, two modified step-up KY converters are interleaved to obtain a high conversion ratio without the use of coupled inductors. In comparison with the conventional interleaved DC-DC converters such as boost, buck-boost, SEPIC, ZETA a...

In this paper a complete multi input-multi output state-space average model for the KY buck-boost converter is presented. The introduced model includes the most of the regulator’s parameters and uncertainties. In modeling, the load current is assumed to be unknown, and it is assumed that the inductor, capacitor, diode and regulator active switches are non ideal and have a resistance in conducti...

Received Jan 8, 2018 Revised Mar 23, 2018 Accepted Apr 11, 2018 Distributed energy source based electricity generation is an essential factor for the economic growth and development of a country. The photovoltaic, fuel cell and battery based power generation offer a high voltage gain. The DC-DC CUK converter based on both buck and boost mode of operation is proposed for high gain dc link voltag...

Photovoltaic system (PV) is widely used in various renewable energy application. The main problem of PV system is how to get the maximum output power which is integrated in microgrid system. Furthermore, the redundancy output power generated by on a distribution system should also be considered. This study utilizes the excess power for energy storage using bidirectional of KY inverse converter....

This paper proposes a three-port Zeta-KY dc-dc converter which is fed with hybrid sources like photovoltaic (PV) cells and batteries. The proposed here multi-input single-output (MISO) structure harnesses the benefits of Zeta KY converters. combination these converters highly advantageous since provides lesser output voltage ripples high gain topology suits well for withstanding load transients...
