A Fast Loss Model for Cascode GaN-FETs and Real-Time Degradation-Sensitive Control of Solid-State Transformers

Sensors, 2023
This paper proposes a novel, degradation-sensitive, adaptive SST controller for cascode GaN-FETs. Unlike in traditional transformers, a semiconductor switch’s degradation and failure can compromise its robustness and integrity.

Parameters Estimation for Constant-Stress Partially Accelerated Life Tests of Generalized Half-Logistic Distribution Based on Progressive Type-II Censoring

Revstat Statistical Journal, 2020
In product-life testing experiments, the accelerated life testing (ALT) is applied to reduce the time and cost of tests. We consider the constant-stress partially ALT model when the lifetime of units under normal conditions follow the generalized half ...

Estimations of accelerated Lomax lifetime distribution with a dependent competing risks model under type-I generalized hybrid censoring scheme

Alexandria Engineering Journal, 2022
In a reliability theory, the statistical inference under accelerated competing risks model have a great significance. This model proposes the assumption of independence of variables for convenience.
