DC Solid-State Circuit Breakers with Two-Winding Coupled Inductor for DC Microgrid
Energies, 2021 Ensuring a protection scheme in a DC distribution system is more difficult to achieve against pole-to-ground faults than in AC distribution system because of the absence of zero crossing points and low line impedance.

The employment effects of working time reductions: Sector‐level evidence from European reforms
Industrial Relations: A Journal of Economy and Society, Volume 62, Issue 3, Page 217-232, July 2023., 2023 Abstract In this paper, we exploit a panel of industry‐level data in European countries to study the economic impact of national reductions in usual weekly working hours between 1995 and 2007. Our identification strategy relies on the five national reforms that took place over this period and on initial differences across sectors in the share of ...
