| Phasor based voltage source converter model. |
OpenIPSL.Electrical.VSD.Generic.PowerElectronics.AC2DCandDC2ACPhasor based voltage source converter model.
The AC2DCandDC2AC component represents the power electronics component of the variable speed drive. The model provides an interface between two terminals. Terminal pin p is related to the grid bus side and terminal pin n is related to the motor terminal bus. The model is an average representation of the switching components of a real variable speed drive, thus being ideal for long simulation durations on phasor dynamic simulations.
The model has one input and one output connectors. The m_input input connector represents the pwn modulation index, while the Vc output connector represents the capacitor voltage value used in the controller logic block.
The modelling of such devices is based, mainly, on the following reference:
