    This paper shows that double-diode rectifiers can generate 12-step voltages by using well-designed line-side reactors, although with relatively large self-inductances. The usage of three-level rectifiers can alleviate this disadvantage. The double three-level rectifier system proposed features the following advantages over conventional transformer-coupled systems: small in size, light in weight, a... View full abstract»

    High-speed electric motor variable speed drives used to drive centrifugal compressors of any size are proven technology, and the examples shown in this paper are exemplary for many other successful inscallations. Economics will not always justify their use, particularly if there is no reliable and economical source of electric power available at site, but most applications can ill-afford not to ev...

    Simplified analytical models for calculation of the induction motor's short-circuit current are presented. Laboratory tests have been performed on two induction motors with low power rating, 26 kW and 122 kW, respectively, in order to measure their short-circuit current. Results calculated according to the available literature have been compared to those acquired by testing. Calculations have also... View full abstract»

    In this article, a PWM control strategy for a three-phase, five-level double converter system is proposed. The proposed method is able to correct the five-level DC potentials, maintain the input power factor at near unity, and achieve adjustable-speed drive. Simulation and experimental results verified the validity of the control strategy. However, large voltage ripples were observed in the experi... View full abstract»

    This article presents 22 configurations of power filters for the harmonic compensation of nonlinear loads. Some of these configurations are novel and result from the newly discovered characteristics of nonlinear loads and circuitry duality, while the others are well known and used in practice. Nonlinear loads can be characterized into two types of harmonic sources: current-source nonlinear loads a... View full abstract»

    Three-phase induction motors are the “workhorses” of industry and are the most widely used electrical machines. In an industrialized nation, they can typically consume between 40 to 50% of all the generated capacity of that country. This article focuses on the industrial application of motor current signature analysis (MCSA) to diagnose faults in three-phase induction motor drives. MCS... View full abstract»
