Power supply harmonics Power supply harmonics 5.1.1 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.
Page 84
Power supply harmonics 5.1.2 Harmonic suppression guidelines in Japan Inverters have a converter section (rectifier circuit) and generate a harmonic current. Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression Guidelines was established to protect other consumers from these outgoing harmonic currents.
