Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). Using MATLAB/SIMULINK, a model was built for the machine featuring three independent frames and a nonlinear, cross coupled flux relation. It has been connected with the corresponding modulator models, where two carrier based modulators have been developed as well as two space vector modulators. The simulation data was then fed into the loss model to calculate the corresponding losses in both machine and converter. This work sho...
