Abstract: A redundant boost circuit configured to compensate for a voltage drop between a power supply and a plurality of loads is provided. The redundant boost circuit includes a first compensator module and a second compensator module. The first compensator module includes a first primary boost circuit and a first secondary boost circuit. The second compensator module includes a second primary boost circuit and a second secondary boost circuit. The first primary boost circuit and the second secondary boost circuit are electrically coupleable between the power supply and a first load. The second primary boost circuit and the first secondary boost circuit are electrically coupleable between the power supply and a second load.

Abstract: A controller for use in a line voltage drop compensation system is provided. The controller includes a processing device and a memory device coupled to the processing device. The controller is configured to determine a resistance of a power transmission line, the resistance of the power transmission line determined at least partially based on a plurality of characteristics of a load and the transmission line. The controller is also configured to generate a control signal to control an output voltage of a boost circuit, the output voltage determined at least partially based on the determined resistance of the power transmission line. The controller is further configured to transmit the control signal to the boost circuit to cause the boost circuit to generate an output voltage to compensate for the voltage drop.

Abstract: A system for compensating a voltage line drop includes a shelving unit comprising at least one receiving port, wherein the at least one receiving port includes a connector. The system also includes a power converter operable to generate a line drop compensated output voltage, and a bypass module physically coupled between the connector and the power converter, wherein the bypass module is operable to selectively switch between providing the line drop compensated output voltage from the power converter to a load and bypassing the power converter to provide an uncompensated output voltage to the load.
