Asymmetrical Multi-Step Direct Model Predictive Control of Nine-Switch Inverter for Dual-Output Mode Operation

open access: yesIEEE Access, 2019
Nine-Switch Inverter (NSI) is composed of two conventional inverters with three common switches. Two sets of three phase ac loads can be connected to the outputs of NSI and independently controlled without any undesirable interaction.

Thermal characteristic analysis of Z-axis guideway based on thermal contact resistance

open access: yesAdvances in Mechanical Engineering, 2018
The Z-axis feeding system of large computer numerical control (CNC) gear grinding machine tools generates lots of heat during processing, which leads to tilt and pitch deformation of the Z-axis guideway and reduces the machining accuracy. In view of this

Application of Predictive Control to Optimize Dynamic Processes in a Given Range

open access: yesСовременные информационные технологии и IT-образование, 2021
The problem of digital control of controlled variables for a dynamic process with their retention in a given range is considered. It is assumed that the change of variables within the range can be arbitrary, but the values of variables must remain within

A Digitally Controlled Power Converter for an Electrostatic Precipitator

open access: yesEnergies, 2017
Electrostatic precipitators (ESPs) are devices used in industry to eliminate polluting particles in gases. In order to supply them, an interface must be included between the three-phase main line and the required high DC voltage of tens of kilovolts ...

Simplified double switching SVPWM implementation for three-level VSI

open access: yesThe Journal of Engineering, 2019
A generalised space vector pulse width modulation (SVPWM) framework for the realisation of all double switching states with a memory-optimised method is proposed to reduce the total harmonic distortion (THD) and to provide neutral point voltage balancing

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.
