Abstract

An uninterruptible power supply system (10) and a driving method thereof relate to the technical field of power conversion and are used for solving the problem of output interruption of the uninterruptible power supply system (10). The uninterruptible power supply system (10) comprises: a first power input (IN1); a second power input end (IN2); a load end (O); a bypass path (B), and at least one main path (M). The bypass (B) comprises a first bidirectional switch (11); the first bidirectional switch (11) is connected with the first power input end (IN1) and the load end (O) and used for controlling connection or disconnection of the first power input end (IN1) and the load end (O). Each main circuit (M) comprises a bus (15) and an inversion output unit (14); the input end of the bus (15) is connected with a second power input end (IN2), and the output end of the bus (15) is connected with the inverter output unit (14); the inverter output unit (14) is also connected with a load end (O), and is used for controlling whether to carry out direct current-alternating current conversion on the current input from the output end of the bus (15) and transmit the current to the load end (O); the voltage value of the current output by the inverter output unit (14) is different from the theoretical voltage value of the current output by the first power input end (IN1).

Description

Technical field[0001]The present application relates to the field of power conversion, and in particular, there is an uninterrupted power system and a driving method thereof.Background technique[0002]In general, uninterruptive power systems (UPS) refers to an automated system for supplying electrical energy in an intermittently supplied electric energy in the event of an electric power interrupt or failure. UPS is a component for powering to electronic devices such as a computer, which requires power to continuous, uninterrupted supply, even when the voltage or frequency of power is changed, or when the electric power is turned off, the UPS can stabilize. Supply electricity, thereby reducing the possibility of electronic device data being destroyed or lost, and avoids the dismissal or malfunction of the electronic device.[0003]Normally, the UPS includes bypass and main path. The ideal UPS is to ensure uninterrupted output of electrical energy through bypass and main road collaborati...
