ABSTRACT: This paper presents a PFCVF (Power Factor Correction) rectifier that
uses a variable frequency source for alternators for electric and hybrid
vehicles application. In such application, the frequency of the signal in the alternator
changes according to the vehicle speed, more over the loading effect on the
alternator introduces harmonic currents and increases the alternator apparent
power requirements. To overcome these problems and aiming more stability and
better design of the alternator, a new third harmonic injection technique is
proposed. This technique allows to preserve a good THD (Total Harmonic
Distortion) of the input source at any frequency and to decrease losses in
semiconductors switches, thereby allowing more stability and reducing the
apparent power requirements. A comparative study between the standard and the
new technique is made and highlights the effectiveness of the new design. A
detailed analysis of the proposed topology is presented and simulations as well
as experimental results are shown.
