A Reconfigurable WPT System With CC‐CV Charging and Power Extension Capabilities

International Journal of Circuit Theory and Applications
ABSTRACT Fast charging is one of the development trends in the EV industry. Based on this, a reconfigurable WPT system with CC‐CV charging and power extension capabilities is proposed in this paper. The proposed WPT system consists of a reconfigurable transmitter and two receivers, where the second receiver utilizes a SAR structure ...

STAU – a review of the Karlsruhe weakest link finite element postprocessor with extensive capabilities

International Journal of Materials Research, 2008
Abstract The inherent brittleness of ceramics led to a probabilistic approach for designing with ceramic materials. For tackling this issue, numerous research projects led to the generation and continuous development of the weakest link postprocessor STAU over the last twenty years.

EXTENSION CAPABILITIES IN TESTING ACTIVITIES OF THE ARMED FORCES OF UKRAINE IN THE CONDITIONS OF REBUFFING ARMED AGGRESSION

Збірник наукових праць Державного науково-дослідного інституту випробувань і сертифікації озброєння та військової техніки, 2022
There is a contradiction between the large volume of weapons, military and special equipment supplied to the Armed Forces of Ukraine from international partners in the conditions of repelling armed aggression produced by domestic and foreign manufacturers and the opportunities for quality assessment of combat, operational and other characteristics of ...

A high frequency ZVS isolated dual boost converter with holdup time extension capability

2006 37th IEEE Power Electronics Specialists Conference, 2006
Bulky holdup time capacitor prevents further increasing power density of front-end AC/DC converters. Instead of using auxiliary circuits, a high frequency isolated dual boost converter is proposed to reduce holdup time capacitor. ZVS can be achieved for both primary side and secondary side switches.

Analysis of lifetime extension capabilities for CubeSats equipped with a low-thrust propulsion system for Moon missions

Acta Astronautica, 2019
Abstract In this paper, we analyze the mission lifetime extension capability for a CubeSat smaller than 3U in a circular lunar orbit at a 100-km altitude, assuming the utilization of a state-of-the-art low-thrust electric propulsion system such as pulsed plasma thrusters with an impulse bit (Ibit) and velocity change (ΔV) below 60 μNs and 120 m/s ...

Novel Design for a Semi-Autonomous Combat Robot with Extension Capability

2009 International Conference on Computing, Engineering and Information, 2009
Teleoperated mobile robotic systems are remotely operated vehicles designed to perform tasks in coordination with human operators. However, teleoperation can be realistically enhanced by a level of automation removing challenges such as constant monitoring.

A high efficiency high power density AC-DC converter with holdup time extension capability

2011 IEEE 33rd International Telecommunications Energy Conference (INTELEC), 2011
This paper proposes a high efficiency high power density AC/DC converter with holdup time extension capability. The proposed AC/DC converter is composed of a proposed two-phase PFC circuit and a ZVS/ZCS current fed isolated converter. During brief interruption of input power, the proposed PFC circuit operates as a boost regulator in order to keep a ...

Implementation of a finite element software system with H and P extension capabilities

Finite Elements in Analysis and Design, 1986
Abstract Some aspects of implementation of an advanced finite element software system is described. The software system, called PROBE, permits assessment of the quality of finite element solutions through p-extension, (i.e. increase in the polynomial degree of elements), and permits the user to control of the quality of finite element solution ...

Differential decay extension capability of Daldinia spp. in wood of Betula pendula, Alnus glutinosa and Fraxinus excelsior

Forest Ecology and Management, 2002
In northern Europe, three closely related Daldinia spp. are found: D. concentrica, D. loculata and D. petriniae. A clear character separating the species is their substrate specificity; stromata of D. concentrica are principally found on Fraxinus excelsior, while stromata of D.

Trefftz Plane Element of Piezoelectric Plate with p-Extension Capabilities

2006
This paper is concerned with the development of Trefftz p-element for two-dimentional piezoelectric materials. Solutions in Stroh formalism for transversely isotropic piezoelectric materials are used for the intra-element displacement and electric potential (DEP) fields together with an independent DEP frame function field along element boundaries. The
