Embodiment Construction
[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0062] Such as figure 2 Shown, implement a kind of method of power supply aging, described method comprises the following steps:
[0063] A. Set the system input current sensor CS1 at the input end of the system or the aging power supply current sensor CS2 at the input end of the aging power supply to detect the total input current Iin of the system or the input current Ip of the aging power supply;
[0064] B. Send Ip or Iin to the harmonic current detection unit of the energy-saving electronic load 20 to obtain its harmonic content signal;
[0065] C. The DC / AC control circuit controls the DC / AC circuit according to the harmonic content signal, so that it outputs grid-connected current with corresponding harmonic content;
[0066] D. Feed back the grid-connected current Ie to the input terminal of the aged power supply 10 for harmonic com...
