Traditional control method of PWM(Pulse Width Modulation) rectifier has good dynamic and steady-state performance, But when PWM Rectifier worked under unbalanced voltages, various harmony powers occurred. Quality of output voltage and input current had been affected. Analyze unbalanced voltage and current through the method of symmetrical component, and two vector-oriented control strategy based on...
Matrix rectifier (MR) is a buck rectifier in nature, which can be reduced from the traditional matrix converter. Like other converters interfaced with the power lines, it hardly avoids the problems caused by the abnormal cases of three-phase input voltages. The existing basic PWM algorithms of MR include current SVM algorithm and switching function algorithm, suitable for normal power supply. In view...
