Package Modelica.Electrical.PowerConverters.ACDC.ControlControl components for rectifiers
Package Modelica.Electrical.PowerConverters.ACDC.Control
A generic controller with signal input and 2*m firing signals is provided in
Signal2mPulse,
where m is the arbitrary number of phases.
Additional topology specific controllers with electrical connectors are also included.
Each controller is equipped with an optional filter to filter the input voltages. By default the filter is enabled.
Such filter is needed if the electrical grid includes a significant voltage drop across the grid impedance distorting the input voltage wave form of the rectifier. The filter included in the PowerConverters library is first order filter with additional compensation of the filter specific phase lag. However, it important to note that the transients of the filters may cause some initial effects which deteriorate after certain periods.
The topology specific controllers allow enabling and disabling of the firing signals. The internal enabling signal of the controllers is either derived from the parameter constantEnable,
if useConstantEnable = true. For if useConstantEnable = false the internal
enabling signal is taken from the optional signal input enable.

Model Modelica.Electrical.PowerConverters.ACDC.Control.VoltageBridge2Pulse
General information about controllers is summarized in Control.
This model provides two firing signal for Graetz bridge thyristor and half bridge rectifiers. The boolean
signal fire_p is assigned to the thyristors connected with the positive DC output pin.
The boolean
signal fire_n is assigned to the thyristors connected with the negative DC output pin.
