In this letter, we present a new measurement technique to evaluate the large-signal output capacitance ( COSS ) of transistors as well as the COSS energy dissipation ( EDISS ), based on the nonlinear resonance between a known inductor and the output capaci ...
The Large Hadron Collider experiments at CERN will use power distribution schemes relying on integrated buck DC/DC converters. Due to the radiation-hardness requirements, the devices used for the development of such converters will have a voltage rating wh ...
In this work, a complete passive UHF RFID system for capacitive sensing applications is developed to be used in food quality monitoring and supply chain management. All the components of the RFID system including the base station, the base station antenna, ...
Nowadays, the scarcity of cheap energy sources requires a particular effort in optimizing the performance of all conversions. The electric power vector is particulary expected to grow in importance, in conjunction with the development of renewable energy s ...
The optimal design of successive approximation register (SAR) analog-to-digital converters (ADCs) requires the accurate estimate of nonlinearity and parasitic capacitance effects in the feedback charge-redistribution digital-to-analog converters (DACs). Si ...
Electrical contactors are relays for interputing high currents (up to 2000 A). They consist of three main distinct parts: the low voltage circuit, the high voltage circuit and the linear actuator that moves the contact. The purpose of this thesis is to des ...
A new isolated DC-DC converter is presented suited for high voltage applications. It is based on the series connection of NPC inverter cells, using semiconductor devices with lower voltage blocking capability than the total input voltage. The galvanic isol ...
This paper presents a family of three transformerless converters (buck, boost and buck-boost) with two specific characteristics: the quadratic static gain as a function of the duty cycle ratio, and the division of the higher voltage level between the two s ...
From the electrical point of view, the body and the anode of high power gyrotrons behave as capacitive loads. A highly dynamic power supply is, therefore, hard to achieve. The MAGY concept (Modulator for the Anode of a triode type GYrotron) embodies an inn ...
This paper is focused on the design, modulation and control of a re-generative non-symmetrical multi-level converter for high-power applications such as oil and gas or mining. The converter is based on standard IGBT modules and the DC-link voltages are cho ...
