The analytical solution for the sub-module voltage ripple equations of a Modular Multilevel Converter (MMC) is derived, based on the knowledge of the external voltage/current magnitudes and enhancing a concept previously presented in literature. In order t ...
The current development of generators and power electric drives is characterized by increased power electronic integration. This evolution concerns particularly the variable speed power units allowing both a higher performance and substantial savings on co ...
This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...
The paper presents an automatic power management system (PMS) designed for the on-line operation of an experimental low voltage microgrid equipped with two power supplies, a kW-class fuel cell (FC) and a photovoltaic (PV) module emulator, along with a 100- ...
This paper reports on energy harvesting from an impact by using a piezoelectric MEMS scavenger. Useful electrical power is generated by the impact of the rotating gear on the MEMS piezoelectric transducer. The design of the device structure was based on bo ...
This paper presents an experimental set-up of a 27 phases input to 3 phases output Poly-Phased Matrix Converter (27x3 PPMC) realised for the real time experimentation of the dedicated control electronics. When the original converter system is dedicated to ...
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 ...
In this paper different cascaded and multilevel topologies are compared for regenerative braking systems using supercapacitors (SC). It shows that the multilevel buck derived topology can beneficiate from both reduced voltage across the inductor and increa ...
In view of the Large Hadrons Collider experiments upgrade, where the inner front-end electronics will require higher supply power, a new power distribution scheme has to be designed. This thesis presents a new and more efficient scheme based on step-down D ...
The upgrade of the Large Hadron Collider (LHC) experiments at CERN sets new challenges for the powering of the detectors. One of the powering schemes under study is based on DC-DC buck converters mounted on the front-end modules. The hard environmental con ...
