Simulations of capacitor currents of figure 5 show that ripple
of capacitor currents is reduced significantly in five-phase
systems. Simulations show that the peak-to-peak capacitor
current in the three-phase system is 3.39 amps compared to
only 0.29 amps for the five-phase system. Therefore, it would
be possible to reduce the size of capacitors in five-phase
systems by a ratio of 9. Reduced electrical capacitance means
small, lighter, and cheaper systems where capacitor current
has direct relationship with the capacitor size and cost.
However, using a 5-phase machine will not reduce the energy
storage requirements to enable continuous operation if the
generator power reduces momentarily. It only will help in
reducing ripples.
