The comparative analysis of UPS topology

An Uninterruptible power supply (UPS) is an important component of radioelectronic equipment, which realizes transformation of the electric power of a net into the electric power with arguments that provide normal operation of equipment. The contemporary topologies used for the construction of a UPS are standby, linearly-on-line, double conversion, and delta-transformation. Comparative analysis of these topologies and their main disadvantages are given.
