ABSTRACT:
At least three alternative stiff current supply power converter topologies provide fixed current to a respective electric load such as a motor, or a non-inductive electric load using either a current source or a pseudo current source. The stiff current power converter topologies reduce the size of passive components within each of the topologies, thus reducing the overall packaging of each of the components and subsystems formed by each of the components. Each of the topologies have a stiff current source, a driver having power electronics formed therein to drive the associated electric load, wherein the stiff current source and the driver operate to deliver a stiff but controllable current to the electric load.
