In the available literature, including reference books on the topic, the spectral analysis of voltage waveforms obtained through the use of pulse-width modulation relies on the assumption of an ideally flat voltage across the DC link of a considered switch ...
Driven by the environmental changes, penetration of renewables and the need for more flexible power grid, DC is reemerging as a basis for future power networks. Already established in the area of HVDC for very long distance transmission, more and more atte ...
Large horsepower induction motors play a critical role as industrial drives in production facilities. The operational safety of distribution networks during the starting transients of these motor loads is a critical concern for the operators. In this paper ...
A slotless magnetically-levitated high speed motor had been designed and build prior to the beginning of this project. This report presents the work done to develop a slotted alternative design to this motor. In this study, the principle of magnetically-le ...
Quasi-two-level PWM operation of modular multilevel converters enables very low module capacitance even at low machine speeds and high torques while the current distortion is tolerable. In this article, the application of nonlinear inductors together with ...
In the last decade, the massive penetration of Distributed Generators (DGs) has brought significant technical challenges to all the aspects related to the planning and operation of distribution networks. Thus, smart grid concept has evolved as a new operat ...
With a large deployment of power electronic converters in various critical applications, condition health monitoring is increasingly becoming important. In modular multilevel converter, submodule capacitance represents one of the critical components, havin ...
Large horsepower induction motors play a critical role in the operation of industrial facilities. In this respect, the distribution network operators dedicate a high priority to the operational safety of these motor loads. In this paper, the induction moto ...
In this article, a soft-switched nonisolated high step-up multi-input dc-dc converter is proposed. The proposed converter has overcome the hard switching problem of the conventional boost three port converter (boost-TPC) by providing zero-voltage-switching ...
The bidirectional LLC resonant converter operated at fixed switching frequency is a preferable candidate for a true dc transformer that does not actively control the power flow. This is due to its naturally stiff voltage ratio regardless of the imposed loa ...
