Formation of control signal for a multifhase interleaved power factor corrector
Keywords:
power source, multiphase interleaved power factor corrector, control signal, total harmonic distortionAbstract
The paper proposes to use circuit topology with a multiphase interleaved power factor corrector in order to improve electromagnetic compatibility of power sources with the network. The method for realization of the multiphase power factor corrector provides operation of each unified phase in the mode of intermittent
current, that is close to boundary current, while the corrector control signal is formed taking into account spectral composition of the input current. This makes it possible to obtain close-to-sinusoidal input current. Using simulation modeling, total harmonic distortion of the circuit under study has been estimated and the
efficiency of the proposed solutions has been confirmed.
