3. Precautions for Use of the Inverter
3.2 Power supply harmonics

3.2

Power supply harmonics

3.2.1

Power supply harmonics

The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor
correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and
transmission path. Take the following countermeasure suppression techniques.

• Differences between harmonics and noises

• Countermeasures

The harmonic current generated from the inverter to the input side differs according to various conditions such as the wiring
impedance, whether a reactor is used or not, and output frequency and output current on the load side.
For the output frequency and output current, we understand that this should be calculated in the conditions under the rated
load at the maximum operating frequency.

NOTE

• The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by the

harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent
protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the inverter.
For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

Item

Harmonics

Noise

frequency

Normally 40th to 50th degrees or less (3 
kHz or less).

High frequency (several 10 kHz to 1 GHz order).

Location

To-electric channel, power impedance.

To-space, distance, wiring path.

Quantitative understanding

Theoretical calculation possible.

Random occurrence, quantitative grasping difficult.

Generated amount

Nearly proportional to the load capacity.

Changes with the current variation ratio. (Gets 
larger as switching speed increases.)

Affected equipment immunity

Specified by standards per equipment.

Different depending on maker's equipment 
specifications.

Countermeasure

Provide a reactor.

Increase distance.

AC reactor

DC reactor

Do not install power 
factor improving capacitor.
