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...

“…This mode of integration is particularly attractive because of its simplicity, low cost of manufacturing and relative ease of implementation [16,23]. The housing acts as a thermal barrier providing thermal isolation between the converter and the machine (particularly the stator windings -a major heat source).…”

“…In the automotive field, the reasons to search for integrated motor drive solutions are the same that pushed, some years ago, at looking for integrated plug and play solutions in the industrial environment [1]. Integrated solutions of electric machines and power electronics could bring strong benefits: to reduce (or eliminate) the cable length between motor and inverter with advantages in terms of overvoltages on the motor side [2], to help to mitigate Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) problems, to obtain a better International Protection Rating (IP), to realize a shared cooling system, and more integrated solutions lead to a strong reduction in the required space for the whole traction drive.…”

PWM Carrier Displacement in Multi-N-Phase Drives: An Additional Degree of Freedom to Reduce the DC-Link Stress

2018

Abstract:The paper presents a particular Pulse Width Modulation (PWM) strategy to reduce the (Direct Current) DC-link capacitor stress for multi-n-phase drives. A multi-n-phase drive is composed of multiple independent systems of n inverter supplying a multi-n-phase electric machine. The paper focused on the investigation of the best phase shifting between carriers for a triple-3-phase drive compared to the 3-phase counterpart in order to reduce the capacitor bench design point. Simulation and experimental results show as the control technique proposed is able to reduce the value of the DC-link capacitor current in any operating condition including fault case. In this sense, the PWM carrier displacement appears like an additional degree of freedom that can be exploited in multi-n-phase drives but also in multi-motor application.

“…Redesign of the drive with the power electronics building block (PEBB) [4] in mind is not just a simple physical redistribution of the components into the housing to save space and wire length, but it is a chance to investigate new possible features, and therefore, new market opportunities. At the moment, higher cost is the main issue preventing their diffusion into the market, but the flexibility and functionalities introduced by IMMD systems is expected to reduce the payback time in the near future; indeed, due to their modularity, on a large scale economy the costs of the IMMD will be cut down [1].…”

Abstract-Future transportation challenges include a considerable reduction in pollutant emissions at a time when significant increase in demand is predicted. One of the enabling solutions is the electrification of transport systems as this should lead to improved operability, fuel savings, emission reduction and maintenance. Whilst state-of-the-art technology has demonstrable benefits there needs to be considerable advancement to meet future transportation affordability and emission targets. Primarily, electrical drives need an improved power density, an increased reliability and a reduced specific cost. For this reason, Integrated Modular Motor Drives (IMMD) present an attractive solution. Modularity leads to redundancy and easier integration. This paper presents a novel speed-drooped control system applied to motors fed by modular paralleled converters. This control technique allows precise speed regulation and power sharing among different segments showing improved fault tolerance and reliability. The design procedure and the power sharing dynamic have been presented and analysed by means of Matlab/Simulink and validated in a 3kW experimental rig, showing good agreement with the expected performances.
