1. A system for controlling a plurality of power converters in a power system, comprising a plurality of power converters forming an array for converting power between a first power level and a second power level,a common input power line coupled to the plurality of power converters on an input side for providing input power at the first power level,a common output power line coupled to the plurality of power converters on an output side for providing output power to a load at the second power level,a controller coupled to the plurality of power converters for controlling a power output of the power converters,an input sensing circuit coupled to the common input power line and to the controller for sensing the input power on the common input power line and transmitting an input power signal to the controller, andan output sensing circuit coupled to the common output power line and to the controller for sensing the output power on the common output power line and transmitting an output power signal to the controller,wherein the controller is configured to control each of the plurality of power converters so as to turn each of the plurality of power converters into an ON state or an OFF state as a function of the sensed input power and the sensed output power such that one or more of the plurality of power converters in the ON state are operating in an optimal power efficiency range.
