Steady-state model for the three-leg shunt-series ac-link power flow controller
(IET (Institution of Engineering and Technology), 2015)
Shunt-series ac links constitute a class of so-called vector switching converters, capable of controlling power flows by synthesising an adjustable series voltage. A novel steady-state model for the recently introduced ...
