A novel three-phase buck-boost AC-DC converter

THREE PHASE AC TO DC CONVERTER:

The converter can operate with input power factor correction and is suitable for applications where a converter needs to operate over a wide range of input ac voltages and/or produce a wide range of output dc voltages. The project will examine how a reduced switched converter with capacitive input filter operates in the boost mode and how a reduced switch converter operates in buck and boost modes.

The buck-boost converter is shown. The output voltage can be either higher or lower than the input voltage.



The buck converter the average input voltage is less than the output voltage .here we can able to control the output voltage by the semiconductor switch like a transformer
