Current sharing between drives
whose motor outputs are
connected in parallel
When used from a 3 phase supply, it is
preferable not to link the DC bus
because the impedance between DC
and each inverter output is just the
impedance of the output chokes. Also,
on the input side, input current sharing
is determined only by making the
temperature of the two rectifiers similar
and by ensuring that both rectifiers see
the same impedance to the line power
supply.
