A multilevel inverter system for an induction motor with open-end windings
TL;DR: The proposed inverter drive scheme is capable of producing a multilevel pulsewidth-modulation (PWM) waveform for the phase voltage ranging from a two- level waveform to a six-level waveform depending on the modulation range.
Journal ArticleDOI
Multiphase Bidirectional Flyback Converter Topology for Hybrid Electric Vehicles
TL;DR: A multi-power-port topology which is capable of handling multiple power sources and still maintains simplicity and features like obtaining high gain, wide load variations, lower output-current ripple, and capability of parallel-battery energy due to the modular structure is proposed.
Journal ArticleDOI
A harmonic elimination and suppression scheme for an open-end winding induction motor drive
TL;DR: By using triangular carrier wave and proper modulating waves for each inverter, the open-end winding induction motor can be operated in the entire modulation range, eliminating all the 6n /spl plusmn/ 1 harmonics coupled with 11th and 13th harmonic suppression.
Journal ArticleDOI
Estimation of global radiation using clearness index model for sizing photovoltaic system
TL;DR: A methodology for developing a simple theoretical model for calculating global insolation on a horizontal surface is described in this article, where the input parameters to the model are the latitude of the desired location and the amount of total precipitable water content in the vertical column at that location.
Journal ArticleDOI
Modelling of switching systems in bond graphs using the concept of switched power junctions
TL;DR: This paper proposes the concept of switched power junctions that is a generalisation of the conventional junction concept in bond graph modelling that ensures that causality remains invariant during mode switching thus keeping the state vector and its dimension time invariant.
