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 ...

Modelling AC Induction Drive in PSpice
Elektronika ir Elektrotechnika, 2007 Problems of modelling of AC induction drive in PSpice are analyzed. Mathematical model of the motor is referred as to system of electric and magnetic circuits, which are coupled magnetically and electrically. Two systems of equations with decomposed motor variables along x and y axis are used to develop model of induction motor in PSpice.

Impact of the motor magnetic model on direct flux vector control of interior PM motors [PDF]
, 2011 The stator-field-oriented, direct-flux vector control has been proven to be effective in terms of linear torque control and model independent performance at limited voltage and current (i.e. in flux weakening) for AC drives of various types.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Impact of PWM strategies on RMS current of the DC-link Voltage Capacitor of a dual-three phase drive [PDF]
, 2014 The major drawback of usual dual three-phase AC machines, when supplied by a Voltage Source Inverter (VSI), is the occurrence of extra harmonic currents which circulate in the stator windings causing additional losses and constraints on the power ...

Coordinated optimization method for IGBT peak voltage suppression of mine-used inverter
Gong-kuang zidonghua, 2022 At present, the methods of optimizing busbar structure parameters, changing gate drive resistance and designing absorption circuit are commonly used to suppress the peak voltage of insulated gate bipolar transistor (IGBT) in mine-used inverter caused by ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
