Analysis of the Zero Overvoltage Switching Phenomenon

IEEE Access, 2022
In common understanding, the fast switching speed of wide-bandgap devices leads to high overvoltage and oscillations, if no countermeasures are taken. Those countermeasures were introduced in the past, and include methods such as build-in gate resistors ...

Hybrid Lanczos-switching models for solving large linear systems and their parallel versions

Journal of Algorithms & Computational Technology, 2023
Lanczos iterative methods for solving a large sparse linear systems typically face the latent breakdown which strikes every time these methods are deployed. A number of approaches to deal with this issue have been investigated.

Ultrafast All-Optical Switch with an Operational Speed Unlimited by the Slow Relaxation of a High Efficiency Nonlinear Refractive Index Change.

The Review of Laser Engineering, 1995
We experimentally demonstrate that the switching speed of a novel symmetric Mach-Zehnder (SMZ) all-optical switch, proposed by the present authors, is unrestricted by normally slow relaxation times of highly efficient, incoherent nonlinear refractions.

Introduction of Active Capacitance Control and Active Parasitic Inductance Control for Zero Overvoltage Switching

IEEE Open Journal of Power Electronics
Zero Overvoltage Switching (ZOS) is a method that enables transistors to perform turn-off transitions at maximum speed, thereby minimizing switching losses, while simultaneously preventing overvoltage oscillations despite the high switching speed ...
