Design of a 1200 V, 100 kW Power Converter: How Good are the Design and Modelling Tools?

2021-08-11T16:56:54+02:00novembre 21st, 2018|Electronique de puissance & convertisseurs, Publications|

During the design of power converter, design mistakes must be avoided, especially for high voltage and high power converters. Simulation tools can be used to help the designers and limit the risks. This presentation will present a design flow approach used to design and validate a 1.2 kV – 100 kW DC-DC converter which was design from die to converter levels and started for a “blank page”. The presentation is organized in four parts. Firstly, the context of the work is introduced. Then, the simulation flow approach used to validate the design is presented. For this part, the presentation will focus on the system level simulation of one inverter, including the power modules. This part will highlight the main limitations of the current simulation tools found by the designers. In the third part, an enhanced approach is proposed to overcome the limitations and the first results are presented Finally, a conclusion will be presented.

This work proposes a method for the full development, from conception to implementation, of the supervisory control of a multi-terminal HVDC (MT-HVDC) system.

Study of Turn-to-Turn Electrical Breakdown for Superconducting Fault Current Limiter Applications

2021-08-11T16:57:02+02:00novembre 2nd, 2018|Appareillage électrique haute tension, Publications|

The rational insulation design of a resistive superconducting fault current limiter (r-SCFCL) requires data gathered from experimental setups representative of the final apparatus. Therefore, an experimental study was performed to characterize the electrical breakdown (BD) of liquid nitrogen (LN2) in the peculiar conditions of a quenching superconducting device.
