D Countermeasures with Reactors against Harmonics Generation
DC/AC Reactors
The
DC reactor and
AC reactor suppress harmonics and currents that change suddenly
and greatly.
The
DC reactor suppresses harmonics better than the AC reactor
. The DC reactor used
with the AC reactor suppresses harmonics more effectively.
The
input power factor of the Inverter is improved by
suppressing the harmonics of the
input current of the Inverter.
Connection
Connect
the DC reactor to the internal DC power supply of the Inverter after shutting of
f
the
power supply to the Inverter and making sure that the charge indicator of the Inverter
turns off.
Do not touch the internal circuitry of the Inverter in operation, otherwise an electric
shock or burn injury may occur.
