Component Not Supported: This
component is not currently supported in TyphoonSim. Adding this component to your
model will prevent you from being able to run your model in TyphoonSim. Please
disable or remove this component from your model before attempting to run your model
in TyphoonSim mode.
A block diagram and input parameters for the Grid Commutated
2L Cell converter are given in Table 1.

A schematic block diagram of the Commuted 2L Cell block is given in Figure 1 with its corresponding
switch arrangement and naming.
Gate drive inputs can be assigned to any of the digital input
pins. For example, if S_1 is set to 1, the digital input pin 1 will
be routed to the S1 switch gate. In addition, the
S_1_logic parameter selects either active
high (High-level input voltage VIH turns on the
switch), or active low (Low-level input voltage VIL
turns on the switch) gate logic, depending on the external
controller design.Figure 1. Schematic block diagram of a Grid Commutated 2L Cell block with corresponding
switch naming
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.
