Research on Control Strategy of Voltage Source Full Power Wind Power Converter

Kongzhi Yu Xinxi Jishu, 2023
In the operating environment of power system with weak grid characteristics, the traditional current source converter control mode is prone to vibration, which increases the crossing difficulty and off-grid probability of wind turbines.

ZVS Turn-on Triangular Current Mode (TCM) Control for Three-Phase Two-Level Converters With Reactive Power Control

IEEE Open Journal of Power Electronics, 2023
High switching frequency operation in power converters leads to a significant reduction in size at the cost of increased switching losses. Thus, soft switching techniques become necessary to reduce the losses. WBG devices have the benefit of low turn-off

Entanglement generation in persistent current qubits

, 2004
In this paper we investigate the generation of entanglement between two persistent current qubits. The qubits are coupled inductively to each other and to a common bias field, which is used to control the qubit behaviour and is represented schematically ...

Universal Current‐Controlled Current‐Mode Filter with Threeinputsand One‐Output Using the Current Controlled Conveyor [PDF]

Active and Passive Electronic Components, 1998
A new current‐mode universal filter is proposed. The filter uses five current‐controlled current‐conveyors (CCCII) and can realise lowpass, highpass, bandpass, notch and allpass responses. The parameters ω0, (ω0/Q0) can be controlled by adjusting the bias currents of the CCCIIs. The proposed circuit enjoys low sensitivities.

$v^1$ Concept: Designing a Voltage-Mode Control as Current Mode With Near Time-Optimal Response for Buck-Type Converters

IEEE transactions on power electronics, 2015
This paper introduces the v1concept that explains how by only measuring the output voltage, designers have information about almost every signal of the power stage.

A 10 V-to-1 V Double Step-Down Buck Converter Using Time-Based Current Mode Control with Minimum Delay Frequency Difference Phase Adder for 1 MHz Operation

Journal of Low Power Electronics and Applications
An extreme step-down ratio buck converter is proposed using a double step-down (DSD) buck converter architecture and a single time-based current mode PWM controller able to generate two non-overlapping control signal phases.

Unified model of voltage/current mode control to predict saddle-node bifurcation

, 2012
A unified model of voltage mode control (VMC) and current mode control (CMC) is proposed to predict the saddle-node bifurcation (SNB). Exact SNB boundary conditions are derived, and can be further simplified in various forms for design purpose.

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.
