Abstract:
A system may include a power converter comprising at least one stage having a dual anti-wound inductor constructed such that its windings generate opposing magnetic fields in its magnetic core and a current control subsystem for controlling an electrical current through the dual anti-wound inductor. The current control subsystem may be configured to minimize a magnitude of a magnetizing electrical current of the dual anti-wound inductor to prevent core saturation of the dual anti-wound inductor and regulate an amount of output electrical current delivered by the power converter to the load in accordance with a reference input signal.
