Abstract

See full text

Current sharing in a power system having multiple PSUs comprises generating and supplying a first power and a second power to a load, and sensing a remote voltage value received by the load based on an accumulation of the first and second powers. The method further comprises determining, by the first PSU, local voltage and current values of the first power, a real impedance value of the first PSU based on the remote voltage value and the local voltage and current values of the first power, and a virtual impedance value of the first PSU based on the real impedance value of the first PSU and a reference impedance value. The method further comprises controlling generation of the first power by the first PSU based on the virtual impedance value of the first PSU.
