System and method for controlling the voltage of bipolar dc power systems

A system (100) for controlling a bipolar DC power system (101) is disclosed. The bipolar DC power system (101) comprises a positive conductor (102), a neutral conductor (103) and negative conductor (104), wherein a positive pole-to-neutral voltage is a voltage between the positive conductor (102) and the neutral conductor (103) and a negative pole-to-neutral voltage is a voltage between the negative conductor (104) and the neutral conductor (103). The system (100) comprises control means for controlling the positive pole-to-neutral voltage and the negative pole-to-neutral voltage, the control means comprising a first voltage converter (105) configured to control a sum or difference of the positive pole-to-neutral voltage and the negative pole-to-neutral voltage, respectively as a function of the sum or difference of the positive output current and negative output current, and a second voltage converter (106). If the first voltage converter (105) is configured to control the sum of the positive pole-to-neutral voltage and the negative pole-to-neutral voltage, then the second voltage controller (106) is configured to control the positive pole-to-neutral voltage, the negative pole-to-neutral voltage, or the difference of the positive pole-to-neutral voltage and the negative pole-to-neutral voltage, respectively as a function of the positive output current, the negative output current or the difference of the positive output current and the negative output current. If the first voltage converter (105) is configured to control the difference of the positive pole-to-neutral voltage and the negative pole-to-neutral voltage, then the second voltage controller (106) is configured to control the positive pole-to-neutral voltage, the negative pole-to-neutral voltage, or the sum of the positive pole-to-neutral voltage and the negative pole-to-neutral voltage, respectively as a function of the positive output current, the negative output current or the sum of the positive output current and the negative output current.
