Abstract :
This paper presents a power converter integrated with PFC and DC/DC which was reliably and effectively applied to low and medium power rating uninterruptible power supply (UPS) system. Compared with the un-integrated topology, the integrated one has more advantages such as lesser components, lower cost, smaller volume, higher power density and so on. In addition, the integrated converter can reduce the current ripple on the bus capacitors, so the capacitor´s life will be prolong. Experiment results are showed to prove the above advantages and excellent performance of the integrated converter
