The growing interest in multiphase electrical drives
has required the extension of control schemes and modulation
techniques already well known for three-phase drives. Specifically,
different and more complex space-vector pulse width modulation
(SVPWM) methods have been developed for multiphase machines
taking into account the increased number of switching possibilities
and the new components resulting from generalized Clarke’s
transformation. In spite of the intensive work undertaken in the
last decade, no SVPWM techniques with common-mode voltage
(CMV) reduction have been developed for five-phase drives. This
work proposes two SVPWM methods that are capable of reducing
the peak-to-peak CMV by 40% and 80% compared to standard
five-phase modulation strategies. Reduction of the CMV is done
at the expense of higher phase voltage and current distortion.
Simulation and experimental results confirm the CMV reduction
and quantify the performance penalties of the proposed methods
