“…Various studies have taken place in order to integrate both capacitors and inductors into the same component [8,9,[33][34][35][36][37][38]. To integrate the capacitance in the same magnetic component as the inductor, the principle of electromagnetic integration is used.…”

“…Over a decade, there has been a shift from traditional separated passive components to integrated ones packed within the motor drive system. The use of passive integration over traditionally designed passive components in motor drive systems offers many benefits [3][4][5][6][7][8][9][10]:…”

“…Therefore, for applications where aforementioned benefits are needed, the use of the integrated technologies seems to be the best solution [8][9][10]. The passive components (discretely placed in the system) associated with the motor drive systems, such as capacitors, inductors, or transformers, occupy a significant amount of space and have added fines and penalties of potential higher weight and loss.…”

“…However, the limitation comes from the thermal management perspective since the several sub-components have been integrated into a single envelope within the system. Without proper thermal management of the whole system, placing these sub-components (i.e., passives or power electronics) close to the machine may cause damage to the drive [8][9][10].…”

With the increased necessity of a high power density and efficient system in aerospace and marine industries, integrated motor drives provide an excellent solution in the modern era. Therefore, a close structural and functional integration of passive components has become a prerequisite task to make a compact overall system. This article reviews the existing motor drives system with integrated passive technologies. To start, the design aspect of the traditional and integrated filter inductors, using the area product approach, is discussed. Subsequently, layouts of traditional and integrated inductors are presented. The available capacitor technologies, suitable for integration, are also discussed with pros and cons of each capacitor type.

Current construction technology and design methods of power converters have reached power density limits that can only be surpassed by changing the way we design and build converters. This paper presents a system integration approach that allows for achieving high power densities. The key issues of the approach, namely hybrid integration in the form of integrated power electronics modules (IPEMs) and integrated thermal and spatial design with optimized air flow are presented in the paper.The spatial and thermal concept of a case study 2.2kW converter for ac drives is presented and the technologies for implementing the IPEMs are listed. The complete system and the experimental results thereof are presented. The converter has a power density of 3.8 kW/l, which is almost four times larger than that of commercially available drives. The approach is not restricted to this application and can be applied to any converter in the medium power range.
