Title: Electroplating rectifier control - optimised by control range subdivision
Inventor: HUEBEL EGON
IPC: G05F1/153
Filed: 1978-07-18
Abstract: The offset of the desired current or voltage for controlled electroplating rectifiers with motorised servo drive is minimised by dividing the entire current or voltage range in two control subranges or more. Each subrange is optimised separately according to its dynamic control action and static dead zone of the controller. This eliminates the present large errors, esp. in the smallest utilised current range, for example when electroplating printed circuit boards. When the lower of two subranges comprises, e.g. 20% of the whole range and the controller dead zone is set to plus-or-minus 2%, the deviation at 10% of the full load current amts. to only plus-or-minus 4% compared with plus-or-minus 20%, if only one range is available.
