A system of multiparalleling a set of voltage source power converters is provided in which any one of the converters may assume the role of a master or a slave. The system can survive the failure of either the master or any of the slaves. A main controller issues PWM command signals to control the current generated in the power converters. The PWM command signal is modified for each power converter such that all of the converters produce the substantially the same current, the current generated in the master unit being used as a reference. A current feedback signal is used to provide the main controller with an accurate estimate of the total current generated by the system.
