Abstract :
A new AC line conditioner with high input power factor and clean AC output voltages for isolating the linear or nonlinear loads is introduced. An AC/DC rectifier with switch-clamped topology is adopted to draw the balanced sinusoidal line current from the AC supply system. A three-leg inverter with switch-clamped topology is adopted in the system to provide clean AC output voltages to the critical or sensitive loads. Experimental results show the validity and effectiveness of the proposed control strategy.
