Aripriharta Aripriharta

hello brother there.

Based on my experiences, you should concern about the source inductance and load inductance (of course you may give the approx. value) and the carrier frequency when calculating the inductance filter in VSD/VFD, (don't forget to put a high speed fuse) And, the capacitance may calculate by using a simple filter equation.

Shrinath Kannan

@Aripriharta, pls help me with this. I'm struggling with overall design of VFD and its integration with that of Grid.

thank you for the answer!
