Interleaved Two Channel Boost Converter for Power Factor Correction using Boundary Conduction Mode

This paper presents the concept of interleaved pulse width modulation to achieve boost converter with power factor correction and regulated DC voltage. The boost converter employs boundary conduction mode and zero current switching to achieve power factor correction. The converter is having a high voltage conversion ratio with wide span of turn ON and OFF period, which will differentiate this proposed converter from the conventional boost converter. The interleaved pulse width modulation will reduce current ripples of input and output currents. The interleaving will also aid to the reduction in size of the inductor and capacitor used for the proposed converter. In this paper the circuit configuration, principle of operation, simulation results, experimental results of the proposed converter are presented.
