| Abstract |
The paper presents a comparison of three-phase diode rectifier circuits using various input resonant
filters for efficient power factor correction. The comparison is based on the normalized volt-ampere
rating of the filter elements that ensures the required total harmonic distortion THD of the input
currents. The input filters considered are series-resonant, parallel-resonant, and hybrid filters. The
diode rectifiers compared are a simple diode-bridge rectifier and diode rectifiers with optimum rerectification
of the third-harmonic ripple power. The latter configurations enable to unite the positive
properties of the circuits using whether only the input filtering or only the ripple power re-rectification
technique. Comparison of the filters considered demonstrates that the parallel-resonant input filter has
the lowest normalized volt-ampere rating. In addition, for such rectifiers the high power factor and low
total harmonic distortion hold in wide range of the load and supply voltage variation. |
