摘要: This paper presents a frequency domain input impedance model for three phase diode rectifier. Compared to literature work, this has two significantly better features: (1) it is valid in wide range, which from below fundamental more than 30 times of frequency; (2) considers the effect ac line and output dc impedance, by setting them as variables model; another word, these can be arbitrary value long circuit works continuous mode. It tested that still accurate even when filter inductor becomes zero. At different parameters, including extreme cases, analytical modeling results numerical simulation present excellent agreement, demonstrates accuracy model. The resulting intended stability analysis large power system involving significant number rectification loads. Detailed derivation presented paper, measurement are also validate results.
