GFL Wave Reference Three-Phase
The wave reference block generates the three-phase reference signal that drives the semiconductor bridge by regulating the real and imaginary components of the instantaneous currents (d and q) according to the input reference current Id and Iq. The wave reference block produces the three-phase reference signal used to drive the semiconductor bridge. This control is achieved by adjusting the real and imaginary components of the instantaneous currents (in the d and q coordinate frames) based on the input reference currents, Id and Iq. The output of the block can be configured to be a duty ratio or instantaneous voltage value. The block contains the current controller and also implements active islanding detection methods (IDM) conjointly with the protection system by modifying the reference current waveform.
