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.
Claims20
A method for power converter current control, comprising:
- 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, having a variable amplitude, in series with a virtual impedance.
An apparatus for power converter current control, comprising:
- a controller for 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, having a variable amplitude, in series with a virtual impedance.
A system for generating power, comprising:
- a plurality of power sources;
- and
- a plurality of power converters, coupled to one another via an AC line and coupled to the plurality of power sources in a one-to-one correspondence, wherein each power converter of the plurality of power converters comprises a controller for controlling an instantaneous current generated by the power converter such that that power converter appears, from the perspective of the AC line coupled to the power converter, as a virtual AC voltage source, having a variable amplitude, in series with a virtual impedance.
