A schematic block diagram of the Tapped inductor Boost 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 S1_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. This same behavior also applies to the AC switch.
The Internal modulator, when selected as the Control parameter, enables you to use the internal PWM modulator for driving the S1 and AC switch instead of the digital input pins. In this configuration, three additional component inputs will be present. The En input is used to enable/disable PWM modulator control, In is used as the reference signal input for the first (S1) internal PWM modulator, and In1 is used as the reference signal input for the second (AC switch) internal PWM modulator.
Model, when selected as the Control parameter, enables you to set the IGBT gate drive signals directly from the signal processing model. The input pin s_ctrl appears on the component. It is a vector input consisting of two signals. The first controls the S1 switch gate, and the second one controls the AC switch. When controlled from the model, the logic is always set to active high.
When in series, L1 and L2 combine to make an equivalent inductor with an inductance value calculated as: , where k amounts to Coupling coefficient parameter. During switching transitions, total energy of the inductors remains unchanged.
Parameters R1 and R2 are resistance values for parasitic resistors of inductors L1 and L2 respectively. Tuning these resistances can significantly dampen the dynamic transitions during set point changes. Leaving these parameter values at 0 will disable these resistors.

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.
