Control
Digital inputs, when selected as the Control parameter, enables the user to assign gate drive inputs to any of the digital input pins.For example, if S1 is set to 1, the digital input pin 1 will be routed to the S1 switch gate. In addition, the S1_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 user’s external controller design.
Model, when selected for Control parameter, enables the user to set the IGBTs gate drive signals directly from signal processing model. The input pin gates appears on the component and requires a vector input of six gate drive signals in the following order: [S1, S2, S3, S4, S5, S6]. When controlled from the model, logic is always active high.
Gate control enabling, when checked, enables using an external PWM enabling digital signal.
PESB Optimization
The PESB Optimization option is available in certain converter models. When PESB Optimization is enabled, all converter's short circuit state space modes will be merged and treated as the same state space mode. For example, if one converter leg within the three phase converter is short circuited and PESB Optimization is enabled, all of the legs within the three phase converter will also be short circuited. This simplification for short circuit modeling can save a significant amount of matrix memory.
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.
