Abstract :
This paper presents a new line-interactive UPS (uninterruptible power supply) system with active power-line conditioning capability. This system uses one power electronic inverter to implement two functions: maintaining uninterruptible power for critical loads, and suppressing power-line harmonics. The system offers efficient and economical power conditioning. Experimental validation is given
