Reduced flicker fusing system for use in electrophotographic printers and copiers

摘要

A new linear power control topology coupled with simple control techniques are presented which virtually eliminate the flicker problem as well as providing excellent power quality over a wide range of power levels. A modified one dimensional LMS control system similar to the standard LMS algorithm with multiple operating points and gain scheduling is also described which when combined with the new power control topology yield a dramatic reduction in flicker while yielding a universal voltage interface for world wide use.
