H Countermeasures against Harmonics With the continuing development of electronics, the generation of harmonics from indus- trial machines has been causing problems recently. The Ministry of International Trade and Industry provided some guidelines in September 1994 for the suppression of harmonics from electrical household appliances and electri- cal equipment in Japan.

Second harmonic: 120 (100) Hz Third harmonic: 180 (150) Hz Second harmonic (120 Hz) Basic frequency (60 Hz) Third harmonic (180 Hz) Problems Caused by Harmonics Generation The waveform of the commercial power supply will be distorted if the commercial power supply contains excessive harmonics.
  • Page 45 Chapter 2 Design Inverter The Inverter as well as normal electric machines has an input current containing harmonics because the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine.
