A schematic block diagram of the 5L NE Type Converter switching block is given in Figure 1 with its corresponding switch arrangement and naming.
Digital inputs, when selected as the Control parameter, enables you to assign gate drive inputs to any of the digital input pins (from 1 to 32). For example, if S1 is assigned to 1, the digital input pin 1 will be routed to the S1 switch gate drive. In addition, the gate_logic parameter is set to either active high (i.e. high-level input voltage VIH which turns on the switch) or active low (i.e. low-level input voltage VIL which turns on the switch). The gate drive logic depends on your external controller design.
Model, when selected as the Control parameter, enables you to set the IGBT gate drive signal directly from the signal processing model. The input pin gate appears on the component and requires a vector input of eight gate drive signals in the following order: [S1, S2, S3, S4, S5, S6, S7, S8]. When controlled from the model, the logic is always set to active high.
Digital Alias
If a converter is controlled by digital inputs, an alias for every digital input used by the converter will be created. Digital input aliases will be available under the Digital inputs list alongside existing Digital input signals. The alias will be shown as Converter_name.Switch_name, where Converter_name is name of the converter component and Switch_name is name of the controllable switch in the converter.
