Numerical simulation of partial discharge current pulse: Comparison between SF6, Fluoronitrile – CO2 mixture and Fluoroketone – CO2 mixture
Understanding of PD phenomena is mandatory to evaluate the performance of PD measurement systems in function of gas composition.
Measuring small differential-mode voltages with high common-mode voltages and fast transients – Application to gate drivers for wide band-gap switches
In power electronics, gate-voltage measurement is used to optimize the design of the gate driver.
Transient stability of power systems with embedded VSC-HVDC links: stability margins analysis and control
Impact of embedded Voltage Source Converter-based High Voltage Direct Current VSC-HVDC links on AC grids transient stability.
Experimental validation and comparison of a SiC MOSFET based 100 kW 1.2 kV 20 kHz three-phase dual active bridge converter using two vector groups
The Dual Active Bridge appears as a promising DC-DC converter topology when galvanic isolation and bidirectional power flow are required. Among its advantages, Zero Voltage Switching allows the switching losses to be significantly reduced.
AC/DC Dynamic Interactions of MMC-HVDC in Grid-Forming for Wind-Farm Integration in AC Systems
This paper studies the dynamic interactions between the AC grids and the DC system. In this work, we focus on MMC-HVDC links interconnecting offshore wind farms and AC systems.
