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.

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

New AC traction drive system with transistor VVVF inverter
Conference Record of the 1991 IEEE Industry Applications Society Annual Meeting, 2002A novel VVVF inverter system for a DC electric car has been developed. A description is presented of the configuration, control method and test results of this system. This inverter system consists of four three-phase transistor inverters series connected at their inputs, four induction motors connected respectively with their outputs, and chopper ...
