“…At t 0 − t 1 , Transistor T A− is already on and carrying the load current (I load ). At t 1 , a FUL starts to happen when T A+ is unintentionally shorted by one of the short circuit failure mechanisms, as presented in [1].…”

“…On the suspension level, these requirements translate to the usage of electromagnetic (EM) suspension, as it is able to respond to the road condition quickly. However, the inverter used in the EM suspension poses a problem, namely the possible failure of the power switches [1]. One of the most probable failure types that can happen in the system is a short circuit in one of the converter's Half-Bridges (HB).…”

“…Due to the unavoidable capacitive coupling between the power circuit and the pick-up coil, the sensed stray voltage will be influenced to some extent. This paper gives an analysis and implementation of SVC and SFC, which is applied for the three-phase system of a 48 V electromagnetic suspension as described in [11].…”

“…At t1-t2, the TA-is already on and carrying a load current (ILoad). At t1, a FUL happens when TA+ is unintentionally shorted by one of the short circuit failure mechanisms, as presented in [1]. In this stage, the drain-source current of TA-increases very rapidly with Lσ being the only limiting factor until the MOSFET reaches its saturation at t2.…”
