| Abstract |
This paper examines the influence of the modulation scheme on the sizing of the input filter in a Pulse Width Modulated (PWM) rectifier system. The examination is based on an analysis of Space Vector Modulation (SVM) schemes using a novel wall model based approach. The impact of using a standard Double Edged SVM scheme is compared with a 60° bus clamped scheme. The filtering requirements and associated filter size to meet the VDE0871 Class A limit for each modulation scheme are considered. The modulation schemes and the associated filter size are compared on the basis of equal switching frequency and equal switching losses. |
