A current flows into the capacitors. The<br />
current is different from the voltage in waveform.<br />

Countermeasures with Reactors against Harmonics Generation<br />
• DC/AC Reactors<br />
The DC reactor and AC reactor suppress harmonics and currents that<br />
change suddenly and greatly.<br />
The DC reactor suppresses harmonics better than the AC reactor.<br />
The DC reactor used with the AC reactor suppresses harmonics more<br />
effectively.<br />
The input power factor of the Inverter is improved by suppressing the<br />
harmonics in the input current of the Inverter.<br />
Note 18.5- to 160-kW Inverters have a built-in DC reactor.<br />
185- to 300-kW Inverters cannot use a DC reactor.<br />
• Connection<br />
Connect the DC reactor to the internal DC power supply of the Inverter<br />
after shutting off the power supply to the Inverter and making sure that<br />
the charge indicator of the Inverter turns off.<br />
!<br />
WARNING<br />
Do not touch the internal circuitry of the Inverter in operation, otherwise an<br />
electric shock or a burn injury may occur.<br />
