ABSTRACT:
By adding a suitable LC filter to the input of a Buck
converter, a high-power-factor buck converter is proposed. The converter can
operate in the discontinuous-output-current mode operation. A Buck converter in
this operation mode features simple control as the constant duty cycle PWM
used. The operation condition of the converter is studied. The validity of
analysis is verified by Simulation and Experimental results.
