Summary:This paper proposes a low cost double conversion power line conditioner with high frequency isolation, high input power factor, full-range input voltage varying among 90Vac-264Vac and 115Vac output voltage. The rectifier with power factor correction is based on flyback converter using the critical current mode control. The inverter is based on full-bridge topology with digital control implemented in a DSPic30F2020 microcontroller. This system is suitable for application with loads which require a high quality sinusoidal voltage. System description, theoretical analysis and experimental results for a 500W implemented prototype are shown in this paper.
