Realisation of a high-speed drive using a BLDC motor, especially that of low and medium power and with rotational speed of up to 40 000 rpm designed for use in aviation appliances, became possible due to rapid progress in electronic power control technology. An increase of both capability and diversity of electronic power circuits results from the increase of semiconductor element voltage and current operational ranges simultaneously with the improvement of their dynamical parameters, as well as from application of up-to-date microprocessor and programmable circuits for control purposes. Choice of topology for a drive system to be used in aviation appliances, including the electronic power converter, is based on the following quality and economy-related criteria: single-phase supply and sinusoidal waveform of power network current; high efficiency and reliability; small overall dimensions; minimum number of semiconductor elements; and low price. Various technical solutions are possible here, concerning both the scope of the power circuit and the control system.

“…It has been shown that power converters operating in cryogenic temperatures have a higher efficiency and reliability, as well as faster switching speeds than those operating at room temperature. Additionally, cryogenic converters have a greater power density than room temperature converters [19].…”

“…Connections and packaging systems create many problems for HTE circuits . On the other hand, LTE operating at cryogenic temperatures are essential in scientific research, like superconducting materials engineering and their industrial applications – magnetic levitation transportation systems, superconducting energy storage systems, in medical diagnostics, astronomical observations, and also in aircraft and space exploration . In addition, electronics cooling itself operates better, which is of great importance for e.g., microwave amplifiers in receivers used in radio astronomy and space communications.…”

“…Semiconductor devices work even better when they are cooled to liquid nitrogen (LN 2 ) temperatures. Field effect devices, like MOSFETs and IGBT, are operating with higher speed, higher current density, and increased gain, shorter time of signal transmission, improved heat transfer, lower power dissipation, and lower noise . It is worth mentioning that semiconductor devices have low‐temperature limits due to the freeze‐out effect of dopants in semiconductors that require a certain temperature to ionize, about 40 K for Si and about 20 K for Ge.…”

“…Passive components change their characteristics at low temperatures in different ways. The change of capacitance of the capacitors depends on the properties of dielectric (poly‐propylene, polyester, polycarbonate, mica, and ceramic) in cryogenic environments . Devices that function using movement of ions, like electrolytic capacitors, drastically lose capacitance at cryogenic temperatures.…”

The electrical properties of highly conductive ITO/Ag/ITO multilayer film at cryogenic temperatures have been presented in the paper for the first time. A good electrical conductivity and high thermal resistance of ITO/Ag/ITO are desirable features at cryogenic temperatures. Elements in ITO/Ag/ITO (AgHT™) were patterned using fiber laser ablation. Close to a linear (R2 = 0.999) relationship between resistance and temperature in the range of 293–55 K was confirmed. The dynamics of resistance changes is of the order of 9 × 10−4 1/K. Carrier concentration and mobility have been determined on the basis of Hall voltage measurements. Structures patterned in AgHT™ conductive film can be seen to be suitable for passive elements of low‐temperature electronics.
