Abstract – 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.
