METHOD AND APPARATUS FOR TIME-DOMAIN DROOP CONTROL WITH INTEGRATED PHASOR CURRENT CONTROL

Abstract:

A method and apparatus for power converter current control. In one embodiment, the method comprises controlling an instantaneous current generated by a power converter such that that power converter appears, from the perspective of an AC line coupled to the power converter, as a virtual AC voltage source in series with a virtual impedance.
