DC Link Inductor Calculation

DC Link Inductor Calculation

DC Link Inductor Calculation

(OP)
I am interested in wondering how to determine the inductance of a DC Link Inductor I am using in my system. I have a 12 pulse source bridge, two 6 pulses in series with each 6 pulse receiving 230VAC. A wye transformer for one 6 pulse and a delta transformer for the other. The DC link inductor will then see about 460Vdc and I have calculated 35.9A according my load. I am just not sure what the inductance should be of this inductor.

Any help is appreciated,

Joe

RE: DC Link Inductor Calculation

There are some input data missing:

- diode rectifier or phase angle control ?
- what condition has to be met
   - certain ripple ?
   - continous current down to xx% of nominal current ?
   - other application specific requirement (e.g. limiting interharmonics)



 

RE: DC Link Inductor Calculation

There is also another very important aspect: is this a CSI or VSI inverter?

CSI inverters rely entirely on the inductor for smoothing while VSI inverters may or may not have a DC reactor. So, we need to know the inverter type as well.
