SYNTHESIS OF VOLTAGES OF UNIFORM PWM IN TIME REGULATION

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2014
The article describes a process of synthesis and qualitative assessment of the harmonic composition of voltages of multiple and single PWM pulses in time regulation, being, along with amplitude, frequency and phase method, one of control methods of an ...

Fault diagnosis method of a cascaded H‐bridge inverter based on a multisource adaptive fusion CNN‐transformer

IET Power Electronics, EarlyView.
The multisource adaptive fusion CNN‐transformer method proposed in this study can provide theoretical and technical support for fault diagnosis of high‐voltage MCHBI. It has a promising potential for engineering applications. Abstract In high‐voltage applications, the number of cascaded H‐bridge inverter units is large, the failure probability ...

Modelling of Salp Swarm MPPT Algorithm‐Based Quadra‐Tied Solar PV System to Minimise Power Loss in Urban Areas During Shading Scenarios

IET Smart Energy Systems, EarlyView.
This research presents a comparative analysis of salp swarm algorithm (SSA) and particle swarm optimisation (PSO) strategies for maximum power point tracking (MPPT) to alleviate the detrimental effects of partial shade on rooftop solar photovoltaic systems in urban settings utilising a quadra‐tied PV array design.

Individual and combined effects of chemical and mechanical power on postoperative pulmonary complications: a secondary analysis of the REPEAT study

Anaesthesia, EarlyView.
Summary Introduction Intra‐operative supplemental oxygen and mechanical ventilation expose the lungs to potentially injurious energy. This can be quantified as ‘chemical power’ and ‘mechanical power’, respectively. In this study, we sought to determine if intra‐operative chemical and mechanical power, individually and/or in combination, are associated ...

Algorithms of Space Vector PWM in Overmodulation Area

Advances in Electrical and Electronic Engineering, 2006
The aim of this paper is the comparison and evaluation of different space vector PWM (SVPWM) strategies enabling the continuous transition from the linear modulation to the six-step mode.

Autologous haematopoietic stem cell transplantation for multiple sclerosis in the UK: A 20‐year retrospective analysis of activity and haematological outcomes from the British Society of Blood and Marrow Transplantation and Cellular Therapy (BSBMTCT)

British Journal of Haematology, EarlyView.
We report the UK experience of autologous haematopoietic stem cell transplantation (AHSCT) for multiple sclerosis (MS) in 364 patients. In our observational study, transplant‐related mortality was 1.4%, Epstein–Barr virus reactivation occurred in 75.9%, while disability progression‐free survival was 83.5% at 2 years post‐AHSCT and 62.4% at 5 years.
