Optimized kW-Range Boost Converter Based on Impulse Rectification with 52 kW/l and 98.6% Efficiency

Elison de Nazareth Matioli, Armin Jafari, Remco Franciscus Peter van Erp

Maximizing the efficiency and power density of dc-dc converters demands parallel optimizations in design and control, especially for variable-frequency converters operating over wide frequency ranges. This work presents the full-scale optimization of a kil ...

Protection Coordination in Marine DC Power Distribution Networks

Seongil Kim

The increasing penetration of renewable energy sources, energy storage systems (ESSs), and DC loads has opened the door to DC technology to pave its way into future grids. The shift has been more obvious in the marine domain supported by track records of i ...

A cost-device efficiency balanced spiro based hole transport material for perovskite solar cells

Mohammad Khaja Nazeeruddin

Although spiro-MeOTAD 1 is a superior hole-transporting material (HTM) commonly employed in perovskite solar cells (PSC), its high cost is one of the major issues holding back commercialization, which has not been resolved to-date. In this article we intro ...

A partially-planarised hole-transporting quart-p-phenylene for perovskite solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Michael Saliba

Herein, we describe the synthesis of a hole transporting material based on a partially planarised quart-p-phenylene core incorporating tetraketal and diphenylamine substituents that show optimal energy levels and solubility for perovskite solar cell applic ...

Design-oriented Modeling of 28 nm FDSOI CMOS Technology down to 4.2 K for Quantum Computing

Christian Enz, Arnout Lodewijk M Beckers, Farzan Jazaeri

In this paper a commercial 28 nm FDSOI CMOS technology is characterized and modeled from room temperature down to 4.2 K. Here we explain the influence of incomplete ionization and interface traps on this technology starting from the fundamental device-phys ...

Load Flow in Multiphase Distribution Networks: Existence, Uniqueness, Non-Singularity and Linear Models

Jean-Yves Le Boudec, Andrey Bernstein, Cong Wang

This paper considers unbalanced multiphase distribution systems with generic topology and different load models, and extends the Z-bus iterative load-flow algorithm based on a fixed-point interpretation of the AC load-flow equations. Explicit conditions fo ...

The key impact of incorporated Al2O3 barrier layer on W-based ReRAM switching performance

Yusuf Leblebici, Jury Sandrini, Elmira Shahrabi, Cecilia Giovinazzo

In this article, we inspected the bipolar resistive switching behavior of W-based ReRAMs, using HfO2 as switching layer. We have shown that the switching properties can be significantly enhanced by incorporating an Al2O3 layer as a barrier layer. It stabil ...

Extension of the Unmatched-Media Time Reversal Method to Locate Soft Faults in Transmission Lines

Mario Paolone

An alternative method based on time reversal to locate solid faults in transmission line networks was recently proposed by Codino et al. in the paper “An alternative method for locating faults in transmission line networks based on time reversal” (IEEE Tra ...

Ultra High-Speed Hardware Emulator for Real-Time Fault Location in Multi-Conductor Power Systems

Maher Kayal, François Krummenacher, François Pierre Gaugaz

This research presents a transmission line model aimed for the fault location in power systems using a method based on the Electromagnetic Time-Reversal (EMTR). The discrete-time model simulates the waves travelling in the line by means of many unit delays ...
