  • Page 39 Wiring Chapter 2-2 Causes of Harmonics Usually, electric machines have built-in circuitry that converts commercial AC Generation power supply into DC power. Such AC power, however, contains harmonics due to the difference in current flow between DC and AC. Obtaining DC from AC Using Rectifiers and Capacitors DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and smoothing the pulsating one-side voltage with capacitors.
  • Page 40 Wiring Chapter 2-2 Countermeasures with DC/AC Reactors Reactors against The DC reactor and AC reactor suppress harmonics and currents that change Harmonics Generation 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.
