“…Most of these models are based on lumped parameter models (Degano et al 2012;Moreira et al 2005;Boglietti et al 2007;Liwei et al 2010;Boglietti and Carpaneto 1999;Moreira et al 2002;Schinkel et al 2006). Distributed parameter based models of induction machine will require many parameters that make extracting those values difficult.…”

In this paper a novel high-frequency model of Induction motor is presented for investigating induction motor behavior in a wide electromagnetic interference (EMI)-frequency range from 100 Hz to 30 MHz. This model is suitable for prediction of common mode current, EMI problems and terminal over-voltage analysis. The model parameters are estimated by asymptotical method using novel differential and common-mode impedance measurements. The values of parameters are limited in a specified range and then optimized using genetic algorithm (GA). A least mean square method is used with GA optimization to solve the identification problem. The proposed model can also be used to predict the high-frequency problems and design EMI filters to improve electromagnetic compatibility limitation in cable fed motor-drive system. In order to validate the proposed high-frequency motor model, novel common-mode and differential-mode measuring tests have been carried out on the 9.3 kW industrial induction motor using a network analyzer in a wide frequency range as described. Very good agreement was seen between the experimental and simulation results of the proposed model in both magnitude and phase.

“…These high frequency problems can result in reducing the system performance; therefore, EMI filters are generally used to suppress electromagnetic emission (Akagi and Shimizu 2008;Shuo et al 2010;Moreira et al 2005;Weber et al 2004).…”

“…Specially developed control schemes, on the other hand, aim to reduce the number of switching incidences that also entail a change of the CM voltage. Example for research on techniques to reduce or eliminate the HF CM voltage at the motor terminals is given by (Wang, 2000;Haoran et al, 2000;Ogasawara, Ayano, Akagi, 1997;Ogasawara, Ayano, Akagi, 1998;Cacciato et al, 1997;Julian, Oriti, Lipo, 1999;Skibinski, Kerkman, Schlegel, 1999;Akagi Doumoto, 2004;Moreira et al, 2005;Hyypio, 2005;Akagi, Tamura, 2006;Akagi, Shimizu, 2008). Work in these areas frequently makes reference to IIBCs, providing important and relevant possibilities of their mitigation.…”

A. Mü tze OVE Today, a search for bearing currents in databases on engineering literature may return hundreds or (depending on the database and any additional filter used) thousands of hits. The degree to which the identified papers address the bearing current topic itself varies. Often, the term is used (as it is common with key words) to reflect the wider context and the topicality of the work that is presented, e.g. a discussion of a new filter topology. Without claiming completeness, this paper provides an overview of the various aspects that have been addressed in literature related to the bearing current topic.Tausende von Treffern: Ü ber umrichterbedingte Lagerströ me, zugehö rige Themen und die Literatur.Eine einfache Suche unter dem Stichwort "Lagerströ me in einer Datenbank fü r Ingenieursliteratur kann zu hunderten oder (abhä ngig von der Datenbank und zusä tzlich verwendeten Filtern) tausenden von Treffern fü hren. Das Ausmaß, mit dem die identifizierten Publikationen das Lagerstromthema behandeln, variiert. Oft wird der Begriff (wie es fü r Stichwö rter ü blich ist) verwendet, um den weiteren Zusammenhang und die Aktualitä t des in der jeweiligen Publikation behandelten Themas, wie z. B. eine neue Filtertopologie, widerzuspiegeln. Dieser Beitrag gibt einen Ü berblick ü ber die verschiedenen mit dem Lagerstromthema in Verbindung stehenden Aspekte, die in der Literatur behandelt werde.

“…There are 4 types of filters are available to eliminate the circulating current they are dv/dt filters (11 kW power level) and dv/dt reactors (110 and 500 kW power levels), sinusoidal filters [16], and common-mode chokes [17]. The elimination of bearing current is 30 to 90% [18]- [19] based on the type of the filter on large rating motors and there is no impact [20] in small rating motors. Moreover the passive filters have more size and weight penalties.…”

Reduction of circulating current is one of the major considerations in inverter fed electrical drives. Diode clamped MLI enables higher output current per phase, thereby rating of the drive gets increased effectively. Various methods of triggering in the inverter legs creates better voltage profile and leads to the enabling of circulating current in the drive system. The induced circulating current flows through the apparatus neutral (N) and supply ground (G) is caused by the existence of parasitic capacitance. This circulating current may cause potential danger especially when parasitic capacitance poses large. In the past, different modulation techniques and conversion topologies have been introduced to minimize the flow of circulating current. However, these techniques lead to complexity, high cost, low voltage profile and efficiency due to lower modulation parameters. This paper proposes PS, POD, PD carrier shifting PWM algorithms for diode clamped MLI to tumbling the circulating current within the each phase of inverter legs. The performances of proposed algorithm, in terms of circulating current, THD, losses and efficiencies are analyzed theoreticallyand are validated via simulation and experimental results.
