Abstract
A method to reduce an inductive voltage surge across a switch array is disclosed. The method comprises the steps of, (a) directing at least a portion of an electric current away from at least a portion of said switch array; and (b) independently opening different portions of the switch array. A system to reduce an inductive voltage surge across an electrical device comprising a current bypass circuit is also disclosed.
Claims28
A method to reduce an inductive voltage surge across a switch array, said method comprising the steps of:
- (a) directing at least a portion of an electric current away from at least a portion of said switch array;
- and
- (b) independently opening different portions of the switch array.
A method of varying resistance of a switch array, said method comprising the step of independently opening different portions of the switch array at independent gating voltages.
A system to reduce an inductive voltage surge across an electrical device comprising a current bypass circuit, said system comprising:
- a subsystem capable of independently opening different portions of the electrical device according to shaped distribution of opening times.
A system to reduce an inductive voltage surge across a switch array, comprising:
- a current bypass circuit;
- and
- a control system comprising:
- a signal generator;
- wherein, the control system is capable of independently toggling any one or more individual switches of the switch array between an open state and a closed state in response to a control signal generated by the signal generator.
