Web20 Mar 2014 · As harmonic mitigation became more prevalent, broadband filters and 18-pulse VFDs appeared on the market. Broadband filters are able to reduce harmonic levels down to 10-15% but are bulky and expensive. 18-pulse VFDs, while expensive, are able to achieve levels down to 3-5% if the phase shifting transformer is properly designed.
