ABSTRACT
The Boost Type Rectifier has been extensively developed and analysed. It offers advantages over traditionally used phase controlled thyristor rectifiers because of its capability for nearly instantaneous reversal of power flow, power factor management, and reduction of input harmonic distortion. Regardless of the cause, unbalanced voltages have a severe impact on the performance of the pulse width modulation (PWM) Boost Type Rectifier. The chapter presents the analysis of the PWM Boost Type Rectifier under unbalanced operating conditions. Ana V. Stankovic and T. A. Lipo proposed new methods for input-output harmonic elimination of the three-phase PWM Boost Type Rectifiers under unbalanced operating conditions. The first method is related to harmonic elimination of three-phase Boost Type Rectifiers under unbalanced input voltages and balanced input impedances. The second method is related to harmonic elimination of the PWM Boost Type Rectifiers under severe fault conditions.
