“…5 b . The 3L‐FC leg control uses the FC topology degrees of freedom reported in [26] and is three‐level modulated (0, E /2, − E /2). For, the two remaining 3L‐NPC legs, and since the NP voltage is no more available, they have to be two‐level modulated and isolated from their mid‐point: their two upper (respectively lower) switches have to be similarly controlled.…”

This study details a three-level hybrid fault-tolerant converter. The definition of an original decoupling solution between the fourth flying capacitor (FC) leg and the three neutral point (NP) clamped-based phases overcomes topology hybridisation issues. Under normal conditions, a control strategy of the FC-based leg leads to a converter NP voltage balance, and decreases the DC side capacitors' volume and cost. Under fault conditions, the presented fault isolation and converter reconfiguration strategies generate a post-fault converter, which is able to operate safely with the added FC-based leg. The proposed topology is an interesting trade-off between converter fault-tolerant capability and its complexity and offers the ability to be simply reconfigured and controlled in the case of switch fault occurrence. Two operation modes under fault conditions are presented and their performances are shown and discussed through simulation results and first experimental tests.

“…Fuses are simple, passive and inexpensive components, able to isolate faulty circuits paths in case of excessive current flow due to a failure. They allow in some fault-tolerant power converters topologies [1]- [3] to avoid spreading failure by separating failed circuit parts, thus enabling the continuous operation of the system. In Fig.…”

In this paper, a first concept of monolithic integration of a fuse on a silicon PiN diode is realized and experimentally characterized. An integrated fuse on PiN diode allows fast cut-off, with low I 2 T (less than 2 A 2 .s) and short pre-arcing times (4 to 6 µs). These fuse-on-diode components are intended for failsafe topologies power converter, aiming for more compact and reliable applications. The fuses were electrothermally designed using Comsol Multiphysics™ and TCAD Sentaurus™ simulations were carried out to study their integration on PiN diodes. Characterization and experimental tests were carried out after components realization.
