This thesis is focused on the design and
implementation of a multiphase interleaved boost power factor corrector (PFC) to achieve a high power factor, low input current harmonics, high efficiency and high power density. A multiphase interleaved boost PFC features the advantages of a PWM boost converter. In addition, the voltage and current ratings of the power switches, and the volumes of inductors, output capacitors and EMI filters can be reduced.
A 800W two-phase interleaved Boost PFC is
implemented in the laboratory. Experiments are conducted and satisfactory results are measured to confirm the effectiveness and the feasibility of the theoretical analysis and design consideration. The
UCC28060 is used as the control IC for the PFC. The power stage consists of two boost PFC converters. It is verified that the current ripples are greatly reduced with
the two-phase interleaved topologies. Thus the two-phase interleaved PFC’s are especially suitable for serving as a
pre-regulator in the high-power applications.
