Minimum Loss Discontinuous Pulse-Width Modulation Per Phase Method for Three-Phase Four-Leg Inverter

open access: yesIEEE Access, 2020
The three-phase four-leg inverter (TPFLI) provides unbalanced voltage to a load or injects unbalanced current to a grid to compensate unbalanced current. However, it has a high switching loss because of the fourth leg. This paper presents a discontinuous

A Snubber Circuit With Clamped Energy Feedback for SiC MOSFETs in Hybrid ANPC Converter

open access: yesIEEE Access
In active neutral-point clamped (ANPC) converters using wide bandgap devices, high switching speeds and inevitable loop parasitics cause voltage overshoot and oscillations during commutation, reducing reliability.

A Gate Driver Based on Variable Voltage and Resistance for Suppressing Overcurrent and Overvoltage of SiC MOSFETs

open access: yesEnergies, 2019
A SiC MOSFET is a suitable replacement for a Si MOSFET due to its lower on-state resistance, faster switching speed, and higher breakdown voltage. However, due to the parasitic parameters and the low damping in the circuit, the turn-on overcurrent and ...

Switching Loss for Generalized Nucleus Detection in Histopathology

open access: yesCoRR, 2020
The accuracy of deep learning methods for two foundational tasks in medical image analysis -- detection and segmentation -- can suffer from class imbalance. We propose a `switching loss' function that adaptively shifts the emphasis between foreground and background classes. While the existing loss functions to address this problem were motivated by the
