Модель магистрально-модульного преобразователя напряжения для расчета его наработки до отказа методом статистического моделирования при смешанном резервировании его каналов
The issues of forming the operating time to failure of a multi-channel voltage converter with a backbone-modular architecture and combined redundancy of its power channels of the “N+1+K” type in statistical modeling are considered. A formal model of the converter with mixed redundancy is proposed, which allows for the implementation of the converter's operating time taking into account channel failures in operation and standby modes, as well as failures of backup channels when they are connected. 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.
