“…These power modules are implemented with unidirectional switches like as IGBTs and fast diodes (DIM200WBS12-A000, SML300MAT06 and FM35R12KE3). Furthermore, some research groups have been using a specially designed power modules to build the matrix converter (Klumpner et al, 2002;Adamek et al, 2003;Simon et al, 2002). Unfortunately, these power modules are not produced in industrial scale, so their cost is very high making difficult their use in a laboratory prototype since if part of the module fails, the entire unit must be replaced.…”

“…It is also mentioned that the PWMSC can operate at higher temperatures due to the use of AC capacitors as opposed to DC capacitors in the SSSC which are quite vulnerable to high temperature applications. In references [16,17], it is presented that the AC link converter topology is more compact size compared to DC link voltage source converter. The three-phase vector switching converter is proposed to develop FACTS controllers which can control the power flow in transmission system [9].…”

Original scientific paperPulse Width modulated based Series Compensator (PWMSC), a newly FACTS device, can modulate the impedance of a transmission line through the variation of the duty cycle of a train of pulses with fixed frequency, resulting in improvement of system performance. In this study, a current injection model of PWMSC is proposed and incorporated in the transmission system model. The purpose of the work reported in this paper is to design an oscillation damping controller for PWMSC to damp low frequency oscillations. We have used the residue method to the linearized equations of the power system for multiple operating conditions and obtained a generalized form which is suitable for different damping controller input-output channels and therefore suitable for different control devices. The case study results show that the proposed controller is very effective to mitigate the power system critical modes of oscillation. Key words: PWMSC, Current Injection Model, Residue Method, Modal Analysis, Damping Controller.Dizajn PWMSC regulatora za prigušenje elektromehaničkih oscilacija. Pulsno-širinski modulirani serijski kompenzator (PWMSC), novi FACTS ureaj, modulira impendanciju prijenosne linije putem promjene popunjenosti niza signala s konstantnom frekvencijom, što rezultira poboljšanim svojstvima. U ovome radu predložen je model ubrizgavanja struje u PWMSC-u koji je nadodan u model prijenosa. Cilj ovoga rada bio je dizajnirati oscilatorni regulator prigušenja za PWMSC u svrhu prigušenja niskih frekvencija oscilatora. Korištena je metoda reziduala na linearizirani model energetskog sustava za različite uvjete te je dobivena općenita forma pogodna za ulazno-izlazne kanale regulatora prigušenja pogodna za različite upravljačke ulaze. Analiza pokazuje da je regulator učinkovit kod ublažavanja kritičnih oscilacija energetskog sustava.

“…Moreover, it suffers from high cost due to the large amount of switching devices (18 IGBTs and 18 diodes) and due to the non-conventional arrangement requiring custom made power modules. The absence of a dc-link capacitor means no decoupling between the input and output, and also the complete absence of ride-through capabilities [96].…”

With increased need for high power density, high efficiency and high temperature capabilities in aerospace and automotive applications, integrated motor drives (IMD) offers a potential solution. However, close physical integration of the converter and the machine may also lead to an increase in components temperature. This requires careful mechanical, structural and thermal analysis; and design of the IMD system. This study reviews existing IMD technologies and their thermal effects on the IMD system. The effects of the power electronics position on the IMD system and its respective thermal management concepts are also investigated. The challenges faced in designing and manufacturing of an IMD along with the mechanical and structural impacts of close physical integration is also discussed and potential solutions are provided. Potential converter topologies for an IMD like the matrix converter, two-level bridge, three-level neutral point clamped and multiphase full bridge converters are also reviewed. Wide band gap devices like silicon carbide and gallium nitride and their packaging in power modules for IMDs are also discussed. Power modules components and packaging technologies are also presented. IntroductionOver the last two decades there has been a shift from traditional physically separated motor and drive systems to more compact, power dense, motor-drive combinations [1]. This new power-dense motor-drive structure combines both the motor and its associated control and drive circuitry within a single enclosure. The earliest records of commercially available motor-drive systems were manufactured by Grundfos in 1991 and Franz Morat KG in 1993 [2].These compact systems have been called a variety of names from 'smart motors' to 'integrated motors', the latter forming the foundation for the new moniker currently identified with these systems [3]. The term 'integrated motor drive (IMD)' is the latest associated with this class of products and is as a result of the success of a TB Woods Inc. manufactured motor-drive registered under the same name [3].IMDs are increasingly being developed and produced by machine manufacturers due to the significant potential benefits they offer. The most significant of these benefits include direct replacement of inefficient direct on line motors, increased power density, lower losses and lower costs compared with separate motor and drive solutions. Technological advancements over the last decade have led to the development of robust electronic components able to withstand the harsh environments required by some forms of integration [4]. By eliminating separate enclosures and long cable runs, the integrated approach promises to lower system costs by 20 to 40% [5].Elimination of transmission cables has economic advantages, including increased reliability due to the removal of the output filter commonly required for long cables. Removal of long cable runs and integration into a single package will also significantly reduce potential electromagnetic interference (EMI). This a...
