The article discusses the main structural schemes of three types of uninterruptible power supply sources: backup; interactive; double conversion. The main functions of which are: performing the function of a backup or emergency power source; performing the function of protective devices, improving the quality of the power supply voltage. The features of operation, advantages and disadvantages of three groups of uninterruptible power supplies are also disclosed. New approaches in the structural and circuit design of uninterruptible power supplies based, including on the use of renewable energy sources are disclosed. Based on the analysis, one of the variants of the block diagram of an uninterruptible power supply with a double conversion of the system is presented and explanations and principles of its operation, as well as advantages and disadvantages are given.
