Description

technical field [0001] The invention relates to the field of electric energy conversion. Background technique [0002] Uninterrupted Power Supply (UPS) for short, is a power supply that can provide short-term continuous power supply when the main power supply fails. It has important practical value in various industries and fields, especially important systems, important departments and important electrical equipment with strong real-time performance. UPS power supply is mainly divided into standby type, online type and standby interactive type. Among them, the output voltage of the online implementation scheme is not affected by the voltage quality of the grid side, and the characteristics of high output voltage quality have been more and more widely used in actual systems. . Compared with the United States and Europe, my country's independent design and manufacturing capabilities of UPS technology and related products are still at a relatively backward level. The master...
