This section describes single-phase two-level H6_5 inverter
A block diagram and input parameters for the H6_5 inverter are
given in Table 1.

Inverter
General
Control (Digital inputs, Model)
S1 (digital input selection for switch S1)
S2 (digital input selection for switch S2)
S3 (digital input selection for switch S3)
S4 (digital input selection for switch S4)
S5 (digital input selection for switch S5)
S6 (digital input selection for switch S6)
Gate control enabling (enables usage of external digital signal to
enable the switching)
Sen (digital input selection for PWM enable)
Digital inputs, when selected for
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.

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.
