Description
This block is used to configure four different switching functions simulated on FPGA. For each switching function, the converter type must be selected, the proper gating signals, and the corresponding measurement.
Mask Parameters
Converter Tabs
Converter type: This is used to choose which converter topology will be simulated by the switching function.
Gate phase A, B, C: This indicates which digital input will be driving the different gates of the chosen converter. It is a vector of 4 values corresponding to gates g1 to g4 as shown in the picture below.
Vdc+, Vdc-, Ia, Ib, Ic measurement: These measurements have to correspond to the one in the eHS model.
Configuration Tab
Controller name: Links this block to an OpCtrl block by entering the same 'Controller Name' as specified in the OpCtrl block. The OpCtrl block controls initialization of the settings of one specific FPGA-based card in the system.
LoadIn port number: This should reflect the LoadIn port used to configure the Switching function configuration block on the FPGA.
Signal name list selection: This value is used to populate the different popup list for the measurement configuration.
Sampling time: This value is the sampling time of the simulation.
Inputs
This block has no input
Outputs
The Status output returns the following values:
| Value | Description |
|---|---|
0 | No error. |
-1 | Block could not be matched with an OpCtrl block (check the 'controller Name' value), or card initialization problem. |
-2 | Internal memory initialization problem. |
Characteristics and limitations
| Direct Feedthrough | N/A |
| Discrete sample time | YES |
| XHP support | YES |
| Work offline | NO |
