Claim Text:
1. An apparatus for operating a power converter of a plurality of serially connected power converters coupled using chaotic democratic control comprising: a DC voltage module for generating a set current value for the power converter to bias a DC source at a set point voltage; and a switching controller for determining an upper threshold and lower threshold based on the set current value, and comparing a system current value to the upper and lower thresholds to determine an operating state of the power converter, where the system current is generated by the plurality of serially connected power converters, wherein when comparing the system current value indicates the system current value is less than the lower threshold, a control signal drives the power converter to switch from the off-state to the on-state; and wherein switching from the off-state to the on-state causes for each remaining power converter of the plurality of power converters operating in the off-state, a decreased probability of switching from the off-state to the on-state.
