Symmetry, Integrability and Geometry: Methods and Applications, 2015 In the article, we describe three-phase finite-gap solutions of the focusing nonlinear Schr dinger equation and Kadomtsev-Petviashvili and Hirota equations that exhibit the behavior of almost-periodic "freak waves". We also study the dependency of the solution parameters on the spectral curves.

A Three-phase to three-phase matrix converter prototype [PDF]
Sba: Controle & Automação Sociedade Brasileira de Automatica, 2012 This paper presents some implementation details of a three-phase to three-phase matrix converter prototype. The bidirectional semiconductor switches were built using discrete IGBTs and fast diodes. Design aspects such as protection against overvoltage and short-circuit, commutation process of bi-directional switches, and input filter are addressed in ...

Three-Phase Busbar Current Transducer [PDF]
, 2019 A true three-phase 1000 A busbar current transducer is based on six micro-fluxgate sensors. Instead of using three independent single-phase current transducers, we use the full information from each sensor.

Flow coupling during three-phase gravity drainage [PDF]
, 2011 We measure the three-phase oil relative permeability k(ro) by conducting unsteady-state drainage experiments in a 0.8 m water-wet sand pack. We find that when starting from capillary-trapped oil, k(ro) shows a strong dependence on both the flow of water ...
