system has a maximum power limit for stable operation. This
limit can be increased by increasing the filter capacitance Cf
or the damping resistance Rf, or reducing the filter inductance
Lf, all of which will affect the filter size, efficiency and cost,
as well as the harmonic attenuation characteristics. Optimal
selection of the converter and drive control bandwidth will
also improve the system stability. Nevertheless this result is
presented for comparison with the time domain simulation in
the subsequent section.
