The present paper addresses the practical implementation in a test bench of different control strategies for the start-up of a varspeed group in pump mode. In varspeed groups using a double-fed induction machine supplied by back to back voltage source inve ...
An input-series/output-series converter dedicated to high power applications is presented. The converter is composed of plural MF transformers based on DC-DC sub-converters. The series connection allows reaching input-voltage levels in the range of several ...
The use of gas turbines in the power generation industry has been increasing. Their demand represents more than 50% of the world market of thermal power plants. Electric power generators using gas turbines as power sources are connected to the turbines thr ...
In this paper, a MEMs relay for high power application is investigated. This relay has to hold a current of the order of magnitude of the Ampere and is subject to harsh environment such as high temperature or vibrations which can lead to a premature dysfun ...
A non-isolated DC-DC converter is presented, based on the current diverter principle. The converter is foreseen for larger photovoltaic plants or other DC collection networks for renewable energy sources. The topology allows the DC-DC conversion as step-up ...
This paper presents a multi-port isolated DC-DC converter for DC applications. A three-port structure is presented, characterized with full bidirectional power flow and simple control. Galvanic isolation is achieved by means of a multi-winding medium frequ ...
Electric Vehicles (EVs) carmakers are heavily confronted by the limited fault ride-through capabilities of actual EVs battery packs. Therefore, this paper introduces a new method of EVs battery packaging based on modular multilevel battery modules as well ...
The paper presents an automated FPGA-based real-time electromagnetic transients simulator for power electronics and power systems applications. The simulator features an automated procedure enabling its straightforward applications to different topologies ...
A non-isolated DC-DC converter is presented, based on the current diverter principle. The converter is foreseen for large power electronic applications where normally the converters are fed from DC supplies at a typical voltage level of around one or two k ...
Medium voltage drives are essential technology for various high power demanding industrial applications. To satisfy ever increasing customer demands, a power extension of the Integrated Gate Commutated Thyristor (IGCT) based 3L-NPC inverter unit, has been ...
