Power conversion system for wireless communication systems

A power conversion system coupled to a power supply that supplies power over a power cable connected to remote radio heads (RRHs), the power conversion system comprising:

• an input that receives input power including an input voltage (VIN) from the power supply, and an output coupled to the power cable;
• one or more DC-DC converters coupled to the output and configured to generate an output voltage at the output, the output voltage generated by adding to the input voltage (VIN), a supplemental voltage (VSUPP) determined from monitored power information to compensate for a voltage decrease on the power cable;
• and
• a control module configured to monitor the power information, the power information including input current measurements of the input power, the input current measurements comprising an input current (IIN) measured on an input of the power conversion system and an input current (IMOD) measured on an input to the one or more DC-DC converters, and a resistance of the power cable;
• wherein the supplemental voltage (VSUPP) is calculated using the power information including the input voltage (VIN), the input current measurements (IIN and IMOD), the resistance of the power cable (Rcable), and a target voltage (Vtarget) at a power input of the RRHs:
