Design
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 off
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.
