Two-Pulse Gate Multiplexer

Multiplex gate input signals to two quadrant chopper

  • Library:
  • Simscape / Electrical / Semiconductors & Converters / Converters

Description

The Two-Pulse Gate Multiplexer block multiplexes two separate voltage signals into a single vector. The vectorized signal can control the gates of two switching devices in a converter, such as a Two-Quadrant Chopper block.

Model

There are two model variants for the block. To access the model variants, in the model window, right-click the block. From the context menu, select Simscape > Block choices.

The model variants are:

  • PS ports — Two-pulse gate multiplexer with physical signal ports. Select this default option to control switching device gates in a converter block using Simulink® gate-control voltage signals. To multiplex and connect Simulink signals to the gate-control inport of a converter block:

    1. Convert each voltage signal using a Simulink-PS Converter block.

    2. Multiplex the converted gate signals into a single vector using the multiplexer block.

    3. Connect the vector signal to the G port of the converter.

  • Electrical ports — Two-pulse gate multiplexer with electrical conserving ports. To control switching device gates in a converter block using Simscape™ Electrical™ Electronics and Mechatronics blocks, select this option. The electrical ports include pairs of electrical connections. Each pair corresponds to the gate and cathode of a switching device in the connected converter block.
