What are the formulas for a lowpass pi or T filter for a given load and
frequency? What I want to do is a lowpass filter for use between an
inverter and a power transformer, to keep the inverter's harmonics (of
60 Hz) out of the transformer. In other words, pass 60 Hz (120V, 2A) to
the load, keep the third and higher harmonics out. The attenuation is
not too critical, just want to keep from overheating the transformer.
