RC Filter or LC ???????
RC Filter or LC ???????
(OP)
Hello
WE are designing a converter to control a induction machine. The converter uses the IGBTs (8KHz) to create the AC current. We know that a filter at the output of converter is necessary. But I can know if I should take a RC filter or a LC filter. Can anyone tell me how and when we chose one of those???
Thanks

for appropriate filters/reactors
The converter output filtering can get complicated and it is very important to be correct for the motor and for the ground and air environments in terms of EMI emissions and ground leaking (stray) currents.

At Siemens we have been using their filter technology (both for EMI and dv/dt & sinusoidal output) for a number of years and had excellent support and technical backup.
There's a lot of useful info on their site.

Congleton for a while, looking after the MM436(SED2) inception with (S) Building Technologies. Now with SBT as Prd.Mgr in Asia Pacific spreading the gospel of Low Harmonic Technology with the SED2!
