High voltage conversion dc/dc converters have perceived in various power electronics applications recent times. In particular, the multi-port converter structures are key solution DC microgrid and electric vehicle applications. This paper focuses on a modified structure of non-isolated four-port (two input two output ports) electronic interfaces that can be utilized (EV) The main feature this i...

Abstract: In this study, a novel, non-isolated, cascade-type, single-switch, high step-up DC/DC converter was developed for green energy systems. An integrated coupled inductor and voltage lift circuit were applied to simplify the converter structure and satisfy the requirements of high efficiency and high voltage gain ratios. In addition, the proposed structure is controllable with a single sw...

DC-DC boost converters are mostly employed in renewable energy system such as photovoltaic system, fuel cell and so on, because these systems generate low output voltage which is not suitable for grid connected power applications. This paper proposes an interleaved boost converter which consists of voltage doubler cell and clamped circuit to achieve large output voltage gain without extremely i...

A novel zero-voltage-switching (ZVS) phase-shift isolated bidirectional DC-DC converter is proposed. It is composed of two symmetrical active-clamped circuits, one on each side of an isolation transformer. The converter can achieve full ZVS in both forward and backward modes even under noload condition. The converter also has a fast response. The operation principle and low-frequency model of t...

Distributed generation is an emerging concept in the electricity sector, which represents good alternatives for electricity supply instead of the traditional centralized power generation concept. Among different distributed generation schemes, fuel cell is expected play a big part due to its inherent advantages. The power density of the quasi-Z-source-based single-phase isolated DC/DC converter...
