| Abstract |
In this paper a new single-phase single-stage Buck rectifier with low effects on the main will be
presented and discussed. This topology allows obtaining an input source current presenting low
harmonic content and behaving as high power factor loads. The output voltage wide range is the main
advantage over the known topologies. In the known topologies the output voltage is lower than the
peak of the input ac voltage. For the new topology the output voltage is lower than the double of the
peak of the input ac voltage. Therefore the output voltage range is increased two times. To achieve
sinusoidal input current and high power factor, sliding mode control of the input current is proposed.
A Proportional Integral (PI) controller is adopted to regulate the output voltage of the converter. |
