Abstract: A current-sharing control circuit, a power supply system and a current-sharing control method are disclosed. One embodiment of the power supply system comprises: multiple CV/CC power supplies connected in parallel to a load, whose nominal output voltages are the same and CV mode to CC mode switching points are adjustable; a current-sharing control circuit including an average load current sensor which senses a total current supplied to the load and outputs a first level linearly related to an average load current equal to the total current divided by the number of the working power supplies, and an output current sensor which senses an output current of each power supply and outputs a second level linearly related to the output current. The control circuit provides feedback signals related to the first level and the respective second levels to the power supplies to adjust their switching points to the average load current.

Abstract: An assembly for adjusting an electrically regulated antenna includes a control device, a motor and a cable. The control device is connected with the motor via the cable, and a shielding material in the assembly for adjusting the electrically regulated antenna comprises alum-glass cloth tape. The shielding material composed of the alum-glass cloth tape is used for improving the electromagnetic shielding effect, particularly the passive intermodulation effect, of an electrically regulated antenna system. The invention further relates to a method for manufacturing the assembly for adjusting the electrically regulated antenna.
