The research of the technology on motor uninterruptible power supply (MUPS)

The voltage fluctuation of power grid is commonly known as interference electricity and is the great threat against continuous production of some enterprises. Comparing to the motor uninterruptible power supply (MUPS) system, the common scheme of UPS for anti-interference electricity has many defects. The structures, principles, characteristics and advantages of MUPS are briefly introduced in the paper and then the solution is found from those shortcomings.
