Advanced Science, EarlyView.High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Design and comparison of quadratic boost and double cascade boost converters with boost converter
2017 14th International Multi-Conference on Systems, Signals & Devices (SSD), 2017Basically, the output voltage in renewable energy sources is improved using the boost converter, which is the key part in a photovoltaic chain. In this converter, the switching frequency is limited; hence the output voltage is reduced. To overcome this problem, two topologies are proposed; the quadratic boost converter results by combining the ...

Modeling and Comparison of Boost Converter With Cascaded Boost Converters
2018Photovoltaic (PV) energy is a very important renewable energy source. The output voltage in renewable energy sources a is improved using DC-DC converters, which are the key part in a photovoltaic chain. Among the classic DC-DC topologies, the boost converter is the most used because of its simplicity and high efficiency.

Qualitative dynamics of the boost converter
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002This work qualitatively analyzes the dynamics of a current programmed mode boost converter operating in continuous conduction mode. The analysis starts with a two-dimensional (2D) map. It proceeds via center manifold theory to a one-dimensional (1D) map. C-bifurcation analysis is applied to the 1D map.

A step up converter is a main component of a micro-grid system, is used to increase the system's voltage. The use of a standard boost converter in high gain applications is not a practical technique upper range of voltage cannot be created and the duty ratio of the switch has to be higher, resulting in significant losses as well as poor efficiency. Due

A novel voltage-bucking/boosting converter: KY buck-boost converter
2008 IEEE International Conference on Industrial Technology, 2008In this paper, a novel voltage-bucking/boosting converter, named as KY buck-boost converter (i.e. 2D converter) is presented herein. Unlike the traditional buck-boost converter, this converter possesses fast transient responses, similar to the behavior of the buck converter with synchronous rectification.
