چکیده
Efficiency is a large concern in power electronics but size and weight must be taken into consideration as well. Power devices in need of thermal sinks for appropriate performance will affect both size and weight. MOSFET devices are the main components in the power electronics world because of their comparatively promising characteristics in power loss and switching performance. The objective of this research is to obtain results as to how the MOSFET device will perform in various temperatures that go as low as liquid nitrogen temperatures. More than one device was tested and compared in order to get the best performing. It is believed Cryogenic operation of MOSFET devices results in improved performance and efficiency. The switching performance of the devices will be analyzed using the Double Pulse Test (DPT). Ultimately, the objective of this research is to design a DC-AC inverter for Boeing & NASA aircraft using the best performing MOSFET device.

Low temperature operation of silicon - on - insulator inverters
This paper describes ,the cryogenic operation of partially depleted Silicon-On-Insulator inverters. As is shown, the floating operation yields a degradation of the transfer characteristics, which increases upon cooling. Additionally, at cryogenic temperatures, hysteresis effects further deteriorate the performance. These observations will be discussed in view of the cryogenic SO1 MOSFET charact...

The deep cryogenic treatment is a complementary operation that is done on a variety of tool steels aimed at improving their abrasion resistance and hardness. In the case of the H13 hot-work steel, which is widely used at high temperatures as a hot-deformation tool, we need to determine the efficiency of subzero treatment on it at the working temperature. In this regard, this paper is focu...
