Description
technical field [0001] The invention relates to the technical field of control, in particular to a line voltage drop control device for remote voltage stabilization of a servo mechanism power supply. Background technique [0002] There is a large inrush current during the working process of the servo mechanism, especially during the starting process. The power supply (usually DC power supply, hereinafter referred to as "servo power supply") that provides electric energy needs to provide a stable voltage for the load of the servo mechanism. Usually, the servo power supply is far away from the load of the servo mechanism (about 10 meters to 50 meters), and the servo power supply supplies power to it through a long power supply cable. When the load of the servo mechanism starts or works, a large current flows through the power cable, causing The voltage drop of the power supply cable is large. In order to reduce and compensate the line impedance of the power supply cable, mul...
