Definition of conditions of transition from corrective recovery to planned recovery strategy of uninterruptible power supply
The problem of the conditions definition of the transition from the corrective recovery to the planned recovery strategy of an uninterruptible power supply, while a reliability is kept on the same level, is considered in this paper.
We consider the uninterruptible power supplies (UPS), which have a modular structure of the power supply unit (PSU). They are designed as a fault-tolerant systems (FTS) with N+M and 2×(N+M) redundant configurations, where N - is number of the PSU modules required to power the workload, and M - the number of the redundant modules.
