A major problem in an isolated DC/DC converters operating at high switching frequencies is the attendant switching losses in the semiconductor devices. This can be reduced by introducing either zero-voltage switching (ZVS) or zero-current switching (ZCS) of the semiconductor switches. This paper deals with the simulation, design, fabrication and experimental evaluation of a novel soft-switching...

A critical problem in building long systolic arrays lies in efficient and reliable synchronization. We address this problem in the context of synchronous systems by introducing probabilistic models for two alternative clock distribution schemes: tree and straight-line clocking. We present analytic bounds for the Probability of Failure and the Mean Time to Failure, and examine the trade-offs bet...

Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) 15 (16.7 traction systems do not have the characteristics behaviour of a typical three-phase medium-voltage distribution system. Switching inductive loads vacuum circuit breaker (VCB) in MV poses familiar challenges as well some unique challenges, such crossing phase change neutral sections. Transformers represent hig...

Abstract The present paper contains an analysis of the operation electric motor aerospace electromechanical servomechanism on a test bench. Particularly, description focuses electromagnetic phenomena three-phase stator circuit and switching phases as function applied control logic rotor position. activity was made possible through construction validation ‘digital twin’ physical model in Simscap...

The article discusses one of the problematic issues operating nuclear power plants - revenue losses caused by staff mistakes. Existing methods and approaches to reducing number such incidents are analyzed. Despite efforts made, problem remains relevant. One directions for equipment failures is study use internal external operational experience. A description given a system preventing recurrence...

A method for solving zero-finding problems is developed by tracking homotopy paths, which define connecting channels between an auxiliary problem and the objective problem. Current algorithms' success highly relies on empirical knowledge, due to manually, inherently selected paths. This work introduces a based Theory of Functional Connections (TFC). The TFC-based implicitly defines infinite fro...

This paper presents leveraging the neural network detector to improve performance of a spin transfer torque magnetic random-access memory (STT-MRAM), where sparse coding scheme is also applied protect user data for asymmetric write failure. The STT-MRAM has recently emerged as good candidate, attracting attention both academia and industry because its unique features such density, non-volatilit...
