An investigation on optimal current mode control for boost-type PWM rectifiers

Abstract-- Static power converters produce harmonics due to
the nature of the conversion process. This paper will investigate
the effect on the power factor of a sinusoidal and Fryze current
reference on a PWM boost type rectifier. It has been shown in
previous papers that a Fryze current ref is best. This paper will
develop a mathematical model, based on the single sided Fourier
expansion. Using this mathematical model it will be shown that
even though a high harmonic content could be present in a Fryze
controlled PWM boost type rectifier, the power factor has been
optimally improved.
