--Discrete sub-system due to passive elements in motor drive require functional and structural integration to make efficient and power dense overall system. Such power dense system is the prerequisite in aerospace and marine applications. This paper presents the design optimization of integrated rotor-less inductors for high speed AC drive applications. Different slot-pole combinations are considered in this process. The single layer (SL) and double layer (DL) windings are chosen with concentrated winding (CW) and distributed winding (DW) configurations. The rotor-less inductors are optimized and compared in this paper with EE core inductor in terms of total losses, weight and AC copper resistance at both fundamental frequency and switching frequencies (10, 15 and 20 kHz). The comparative analysis between EE core and rotor-less inductors has shown a significant reduction in total losses and AC copper resistance at both fundamental frequency and all switching frequencies.

“…In parallel, power density has to be increased in order to reduce weight and costs. Efforts have been made in the field of reducing power electronics size and increasing the level of integration by embedding passive filters into the PCB, using novel magnetic materials with improved characteristics or using pressure contacts for implementing chip level interconnection as presented in [1].…”

A highly integrated inverter for open-end winding machines is designed and build. This paper presents the design of a 6-phase full-bridge inverter for driving an open-end winding machine for electric vehicles. The inverter consists of six fullbridge phase modules that are arranged in a hexagonal shape inside the motor housing. DirectFETs with double-side cooling are used as switching elements. Each module has its own bank of ceramic capacitors. A low-inductive layout allows continuous operation in the nominal operating point at a dc-link voltage of 145V, which is extremely close to the breakdown voltage of the DirectFETs of 150V. In the nominal operating point with a dc-link voltage of 125V, a maximum efficiency of η = 97% is reached.

“…This leads to a separate sub-system which in turn results in a lossy and bulky overall system. In order to overcome these drawbacks the integration of passive components need to be introduced both from functional and physical point of view [1][2][3][4][5].…”
