Super Lift Luo

Description of the Super Lift Luo converter in Schematic Editor.

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 Super Lift Luo converter are given in Table 1.

  • Control (Digital inputs, Internal modulator, Model)
  • S1 (digital input selection for switch S1)
  • S1_logic (active high, active low)
  • Gate control enabling (enables usage of external digital signal to enable the switching)
  • Sen (digital input selection for PWM enable)
  • Sen_logic (active high, active low)
Weight = 1

Digital inputs, when selected as the Control parameter, enables you to assign gate drive inputs to any of the digital input pins. 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.

Internal modulator, when selected as the Control parameter, enables you to use the internal PWM modulator for controlling the S1 switch instead of the digital input pins. In this configuration, two additional component inputs appear. The En input is used as enable/disable and In is used as the reference signal input for the internal PWM modulator.

Model, when selected as the Control parameter, enables you to set the IGBTs gate drive signal directly from the signal processing model. The input pin gate appears on the component and requires one element input which controls S1 switch gate. When controlled from the model, the logic is always set to 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.
