Single‐switch coupled‐inductors‐based high step‐up converter with reduced voltage stress

open access: yesIET Power Electronics, 2023
This paper proposes a non‐isolated DC‐DC high step‐up converter. To achieve a high voltage conversion ratio and overcome the problems related to near unity duty‐cycle of the conventional boost converter in high step‐up applications, coupled‐inductors ...

A new zero-voltage-transition converter for switched reluctance motor drives [PDF]

open access: yes, 1998
Firstly, a new zero-voltage-transition (ZVT) power converter for switched reluctance motor drives is presented. The proposed ZVT converter possesses the definite advantages that both main transistors and diodes can operate with zero-voltage switching ...

Isolated High Step-Up DC–DC Converter With Low Voltage Stress

open access: yesIEEE Transactions on Power Electronics, 2014
Fuel cell stacks and photovoltaic panels generate rather low dc voltages and these voltages need to be boosted before converted to ac voltage. Therefore, high step-up ratio dc-dc converters are preferred in renewable energy systems. A new Z-source-based topology that can boost the input voltage to desired levels with low duty ratios is proposed in this

A High Gain Two-Winding Switched Coupled-Inductor Network

open access: yesInternational Transactions on Electrical Energy Systems, 2022
Summary. This paper proposes a new high-gain quasi-Z-source network (qZSN) with a switched-coupled-inductor (SCL). By employing a two-winding SCL within the impedance network, the proposed topology offers high voltage gains with relatively low shoot ...

Evidence for realignment of the charge density wave state in ErTe$_3$ and TmTe$_3$ under uniaxial stress via elastocaloric and elastoresistivity measurements

open access: yes, 2022
We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides ($R$Te$_3$ for $R$=Er,Tm) as a function of in-plane uniaxial stress.
