Harmonic mitigation for AC thruster & small propulsion drive applications

摘要

The use of electric motors to drive ships' propellers is not new. In 1929, two US vessels, Virginia and California, owned by the Panama Pacific Line were the largest built US steamships at the time and plied between the US Atlantic and Pacific coasts. Each used two 6750 shp DC motors for main propulsion. During WWII, DC motors were used to drive the majority of the hundreds of US built T2 tankers, six of which are still in service today, four in commercial use and two in the US maritime reserve.
