Model of Voltage Converter with Redundancy of Power Channels for Calculation of Its Operating Time in Statistical Modeling
P. 142–149.
Zhadnov V. V.
The problems of forming the operating time to failure of multi-channel voltage converter for statistical modeling are considered. A formal model of the converter with “N out of M active redundancy” is proposed, which allows for the calculation of the converter's operating time taking into account changes in the electrical load of the channels in case of failures. The developed model is created within the limits of assumptions and the restrictions accepted in operating standard documents. The possibility of reducing the computational costs when applying this model in statistical modeling is shown.

Soil respiration (SR) is a main component of the carbon cycle in terrestrial ecosystems,
and being strongly affected by changes in the environment, it is a good indicator of the ecosystem’s
ability to cope with climate change. This research aims to find better empirical SR models using
25-year-long SR monitoring in two forest ecosystems formed on sandy Entic ...
