Abstract
A control circuit for current converter valves includes at a user-specific request unit, a digital transmission unit, and at least one interchangeable system-specific control unit. The control unit includes at least one control circuit with a digital interface, a digital processor and analog components for directly controlling the at least one current converter valve.
Claims11
A control circuit for a current converter, comprising:
- at least one request unit;
- at least a first digital processor and at least a first digital interface in said request unit;
- at least one control unit;
- at least a second digital processor and at least a second digital interface in said control unit;
- at least one analog processor in said control unit in controlling communication with said current converter;
- and
- at least one digital transmission unit operably connecting said at least one request unit to said at least one control unit, whereby data transmissions between said request unit and said control unit are operably effective during a use to provide an error free circuit control for said current converter.
4 more elements
A control circuit for a plurality of current converters, comprising:
- at least one request unit;
- at least a first digital processor and at least a first digital interface in said request unit;
- a plurality of control units operably interconnected in a series;
- each said control unit in operable control of at least one of said plurality of current converters;
- at least a second digital processor and at least a second digital interface in each said control unit;
- at least one analog processor in each said control unit in controlling communication with respective ones of said plurality of current converters;
- and
- at least one digital transmission unit operably connecting said at least one request unit to at least a first of said plurality of control units, whereby data transmissions between said request unit and said first of said plurality of control units are operably effective during a use to provide an error free control circuit between said plurality of current converters and said request unit.
