Abstract
The system and method for dynamically reducing the peak electromagnetic interference produced by a group of electrical or electronic switching devices connected to a common communications bus. The system and method includes a fixed range of frequencies that includes frequencies emitted by the group of switching devices during normal operation and subranges of frequencies within the fixed range of frequencies, each subrange of frequencies being associated with a unique bus address of one switching device in the group of switching devices. Each subrange of frequencies being determined by the unique bus address of its associated switching device and characteristic weights dynamically determined and/or assigned to its associated switching device and/or load by a microprocessor implemented algorithm.
