Certainly A high power chopper switching at a high frequency can produce a lot of harmonic energy, no question about that. This application would be switching at a much lower rate, probably less than once per second. Also, the current being switched is only the field current of the alternator. Given that the residual magnetism in the field does not instantly change, the 140 amps will not instantly change, and so the harmonic energy in the output is far less. So the two applications are a bit different. BUT thanks for mentioning the fact that precautions must be taken.
