Resonant link inverters for traction applications
IEE Colloquium on Resonant Systems, 1995The replacement of traction motor-alternator (MA) sets by the static power converter as a source of auxiliary power meets many of the requirements in terms of reduced maintenance and increased flexibility. However, these power converters are usually based on conventional 'hard-switching' technology and tend to be larger than equivalently rated MA sets.

Archives of physical medicine and rehabilitation, 1978
The effect of inverted positioning on spinal length and electromyographic (emg) activity of superficial lumbar area musculature was investigated in 20 healthy men. Spinal length tape measurements were taken with subjects first sitting erect and after 1 minute in the inverted position. An integrated bioelectric monitoring system was used to quantify emg

Controllers for traction inverter drives
2017The authors present a study of two different types of controllers for a traction voltage source inverter (VSI) drive. The first is a simple scalar control scheme which ensures constant torque operation down to low motor speed. With this controller the inverter V/f characteristic is automatically varied to compensate for different levels of motor load ...

A Minimally Invasive Gradual Traction Technique for Inverted Nipple Correction
Aesthetic Plastic Surgery, 2012An inverted nipple affects not only the aesthetic appearance of the breast but also breastfeeding. Most surgical procedures can cause injury to normal lactiferous ducts and sensory dysfunction. The authors present a simple, safe, and minimally invasive technique for treating inverted nipples.A distracter was made using the distal end of a 5- or 10-ml ...

Invertibility versus Lagrange equation for traction free energy-minimal deformations
Calculus of Variations and Partial Differential Equations, 2014Let \(X, Y \subset \mathbb{C}\) be bounded Jordan domains of the same topological type and let \(\mathcal{M}_2(X, Y)\) denote the space of monotone mappings \(g: \overline{X}\overset{\text{onto}}{\longrightarrow} \overline{Y}\) of finite Dirichlet energy.

Comparison of efficiency measurement techniques for electric vehicle traction inverters
2015 International Conference on Electrical Engineering and Informatics (ICEEI), 2015Performance evaluation of a high-resolution computer based efficiency measurement system for electric vehicle (EV) traction inverter is given. First, a simulation study is carried out to determine the upper limit of the EV traction inverter efficiency curve. Then, experimental efficiency measurements are completed.

Inverter Drive System Stability for Traction Applications
2005 IEEE Vehicle Power and Propulsion Conference, 2005The inverter drive system stability is a classical problem but not understood widely and fully by the industry. Especially for railway traction applications with substations and network distributed parameters also taken into consideration, the question becomes very complicated and so far, there is no satisfactory analytical method or model to cover the
