6.4 Operating the Inverter Using Single+-
Power
Sw
li
single-phase power supply is used
to
operate the inverter only
2/3
of the diodes will be used,
and ripple current of the capacitor will increase compared
to
operation with three-phase power
supply, resuiting in higher temperature rise of the converter and
the
capacitor. Operating the in-
verter using a Single-phase power supply requires derating the output current.

Wionr on operating
the
Inverter using singlsphasc
power
supply
(1)
Connect the single-phase power suppty
to
the terminals
R
arid
S
of
the inverter.
(2)
If
capacity
of
the power supply is insufficient, the
output
voltage will
become
unstable under
changing load conditions. Therefore,
be
certain the power supply is adequate.
