An Improved Three Level Integrated Ac-Dc Converter
Here an improved three-level integrated ac–dc converter is presented. This converter improving or boosting power
factor correction. And also this converter topology is advanced than previous ac-dc converters mainly the converter is
operating with two independent controllers. An input controller is used to power factor correction and it regulates the dc bus,
and the output controller is used to control the output voltage of this converter. The input controller prevents the dc-bus
voltage from becoming excessive. The paper explains the operation of an improved version of new converter and its
procedure for proper design. Simulation results are obtained using mat lab.
