Anordning för minskning av den tredje övertonen

摘要

The coils (2a-2c) and capacitors (4a-4c) are coupled in series between each phase and zero, so that they form a series resonance circuit (1) for the third overtone or an odd multiple thereof. ELECTRONICS - PREFERRED FEATURES : Resistors (5a-5c) are arranged in series with the coils and capacitors between each phase and zero.
