| Abstract |
A new fully controlled single-phase power-factorcorrector
(PFC) buck topology is presented. This new topology
has several advantages over the classical fully controlled singlephase
PFC buck topology. The wide ranging output is one of the
main advantages since the output voltage can be doubled.
Another advantage is the higher efficiency of this converter. The
control strategies for the output dc voltage and input ac current
are also presented and discussed. To achieve sinusoidal input
current and high power factor, a sliding mode control of the
input current is proposed. A Proportional Integral (PI)
controller is adopted to regulate the output voltage of the
converter. |
