Adjustable unbalanced current controller for tranformerless PV generation to suppress DC voltage ripples of inverter in low‐voltage ride‐through (LVRT) operation [PDF]
IET Renewable Power Generation, 2022 Abstract Low voltage ride‐trough (LVRT) feature is compulsory for each grid‐connected inverter to support the grid by injecting reactive power in low voltage conditions. It is well known that the operation of an inverter in a normal grid condition is different from its operation in a faulty one.
