In this paper, a high current pulse power supply for the feeding of a flash lamp has been developed, on the base of a multilevel converter with cascaded cells. The pulsed high power is provided by capacitive energy storage, directly connected to the cells ...
Rectifiers are important energy converters and henceforth crucial building blocks for RFID applications. In the first half of the work, we have presented a design methodology for matching the rectifier input impedance with the antenna to maximize the recti ...

This paper presents the control design of a multilevel modular DC/DC converter for regenerative braking systems in mobile applications. The proposed control scheme is able to control the energy flow between supercapacitors and the DC link and equalizing th ...
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 ...
State-of-the-art low voltage (LV) medium and high power variable speed drives are voltage source converters. Frequently, frond-end stage is a diode rectifier. To reduce the amount of input current harmonic,, multi-pulse rectifiers are used. Due to the high ...
Industrial applications often require two (or more) variable speed electric drives, which have to be controlled independently. An example is a centre-driven two-motor winder, where ac machines are traditionally supplied from their individual three-phase vo ...
in this paper, we present kinetic simulation results of plasma parallel transport in the stationary and ELMy scrape-off (SOL) layer. We demonstrate that number of kinetic factors describing SOL are strongly nonuniform and evolve during the ELM. Power loads ...
InAlGaAs/AlGaAs-based wafer-fused long-wavelength VCSELs with tunnel junction injection emitting in the 1310 nm and 1550 nm bands show high single-mode output and high speed modulation capabilities of 10 Gbps. Fundamental emission close to 6 mW at room tem ...

The feeding device enables a charge (1) to be fed with relatively weak medium power on the one hand, and strong power points on the other, due to energy storage condensers (21) placed in a series. Each of said energy storage condensers (21) is linked to an ...
In high energy physics and space applications it becomes mandatory to solve specific problems concerning the power supply. In both cases, it exists a harsh radiation environment and the presence of external electromagnetic perturbations. The former prevent ...
