DOUBLE-DELTA-WINDING SYSTEM WITH NEUTRAL-POINT-CLAMPED CONVERTERS CONTROLLED BY SYNCHRONOUS MULTI-ZONE PWM

Праці Інституту електродинаміки Національної академії наук України, 2020
In this paper, algorithms of the universal scheme of synchronous multi-zone modulation have been developed and dis-seminated for adjustment of two neutral-clamped inverters of double-delta-winding system (which is perspective for ap-plication in high ...

Organic magnetoresistance under resonant ac drive [PDF]

, 2013
Motivated by a recent experiment, we develop a theory of organic magnetoresistance (OMAR) in the presence of a resonant ac drive. To this end, we perform a thorough analysis of the dynamics of ac-driven electron-hole polaron pair in magnetic field, which

A Novel and Cost-Effective Drive Circuit for Supplying a Piezoelectric Ceramic Actuator with Power-Factor-Correction and Soft-Switching Features

Micromachines, 2021
This paper proposes a novel and cost-effective drive circuit for supplying a piezoelectric ceramic actuator, which combines a dual boost AC-DC converter with a coupled inductor and a half-bridge resonant DC-AC inverter into a single-stage architecture ...

Nonequilibrium depinning transition of ac driven vortices with random pinning

New Journal of Physics, 2017
We study the critical behavior associated with transient dynamics of vortices near the depinning transition by an ac drive. From ${I}_{{\rm{ac}},{\rm{e}}}$ – ${V}_{{\rm{ac}},{\rm{e}}}$ curves at different frequencies f , where ${I}_{{\rm{ac}},{\rm{e ...

Comparative Analysis of PWM AC Choppers with Different Loads with and Without Neural Network Application

Wasit Journal of Computer and Mathematics Science, 2023
In this paper, we focus on the "Artificial Neural Network (ANN) based PWM-AC chopper". This system is based on the PWM AC chopper-encouraged single-phase induction motor.

Generalized Carrier-Based PWM Method for a 12-Switch Converter

Open Engineering, 2016
This paper proposes a generalized carrier-based pulse-width modulation (CBPWM) method for a 12-switch converter feeding three independent loads. The converter topology is part of the (3N + 3)-switch converter family where N is the number of outputs (N ...

Ratchet Effect and Nonlinear Transport for Particles on Random Substrates with Crossed ac Drives

, 2005
We show in simulations that overdamped interacting particles in two dimensions with a randomly disordered substrate can exhibit novel nonequilibrium transport phenomena including a transverse ratchet effect, where a combined dc drive and circular ac ...

Evaluation Method of Bogie Outer Positioning Anti-rolling Torsion Bar Structural Strength

Chengshi guidao jiaotong yanjiu
Objective In order to solve the TBS (torsion bar shaft) torsional stiffness and strength for the outer support anti-rolling device in railway vehicles, an analytical method of introducing the TBS deformation coordination conditions is proposed.

Transverse phase-locking in fully frustrated Josephson junction arrays: a new type of fractional giant steps

, 2003
We study, analytically and numerically, phase locking of driven vortex lattices in fully-frustrated Josephson junction arrays at zero temperature. We consider the case when an ac current is applied {\it perpendicular} to a dc current.
