power consumption

This paper presents the design and implementation of an I²C level shifter using the AM1U1420 single-chip solution. The device enables seamless voltage translation between different I²C logic levels, ensuring reliable communication between components operating at varying supply voltages. The AM1U1420 can integrate bidirectional level shifting functionality, reducing the need for external components and simplifying circuit design. We analyze its electrical characteristics, performance metrics, and practical application scenarios.

The paper considers a method of increasing the energy efficiency of the traction power consumption during operation of a non-autonomous electric rolling stock equipped with an onboard energy storage. The idea is to use the onboard energy storage of the electric braking as an additional power source for the traction electric drive in the process of vehicle acceleration and to coordinate its work with the power supply system.

In the paper methods of construction of mathematical models intended for the power consumption forecasting are discussed. Alternative method of forecasting of defined object using discrete macromodels which allows to conduct quantative analysis of characteristics of the electric energy consumption in the future using known previous data obtained during the field test is proposed.

The paper is concerned with a method intended for forecasting electric power consumption using discrete macromodels of daily and annual electric power consumption of defined objects. The method provides the possibility of estimating qualitative characteristics of future electric power consumption based on known prior data.
