The presentation shows a submodule design for a 2 kV, 1 MW integrated modular motor drive (IMMD) for aviation applications. IMMD system and submodule structures are illustrated and the design challenges are introduced. The gate drive design, busbar design and partial disharge (PD) related studies for the submodule are discussed in detail. The submodule testing results are presented at the end. Double-pulse, short-circuit, and H-bridge test results validated the electrical performance of the sub-module. Preliminary PD tests show that the submodule is free of PD at low pressure of 87 Torr, which is the air pressure at 50,000 feet above the sealevel. The full scale inverter formed by these submodules is expected to achieve an efficiency over 99% with a power density of 35.36 kW/kg.

Submodule Design of a 2 kV 1 MW Integrated Modular Motor Drive for Aviation Applications

The aim of ESSCIRC and ESSDERC is to provide an annual European forum for the presentation and discussion of recent advances in solid-state devices and circuits.
The level of integration for system-on-chip design is rapidly increasing.

This is made available by advances in semiconductor technology. Therefore, more than ever before, a deeper interaction among technologists, device experts, IC designers, and system designers is necessary. ESSCIRC and ESSDERC are governed by a common Steering Committee and share Plenary Keynote Presentations and Joint Sessions bridging both device and circuit communities.

Highlights:
* 3 joint keynote presentations
* 3 keynote presentations ESSCIRC
* 3 keynote presentations ESSDERC
* Invited papers with overall coverage of all aspects of advanced devices and circuits
* Presentation of IEEE and ESSCIRC/ESSDERC Awards
* Educational Events

The IEEE Workshop on Wide Bandgap Power Devices & Applications (WiPDA) provides a forum for device scientists, circuit designers, & application engineers from the Power Electronics & Electron Devices Societies to share technology updates, research findings, experience & potential applications.

This presentation reports the experimental results of the fabricated 4H-SiC Lateral Junction Field Effect Transistor (LJFET) and cell-to-cell integrated Lateral Bi-directional JFET (LBiDJFET). It was found that the reverse conduction characteristics of SiC LJFET were better than the forward conduction characteristics in terms of on-state resistance. The conduction mechanism of LBiDJFET can be described by the series connection of the forward and reverse conduction of LJFETs. This intriguing behavior of the cell-to-cell integration approach is promising because it can greatly reduce the wafer area consumed while achieving the bi-directional functions.
