The voltage/current with a frequency that is an integer multiple of the fundamental frequency. The fundamental frequency depends upon the commercial power supply frequency. In Japan, the commercial power supply frequency is 50 or 60 Hz, so the power supply harmonics are, for example, double or triple that frequency, i.e., 100 and 150 Hz, or 120 and 180 Hz.
