  • Twelve-Pulse Gate Multiplexer block

Description

The Twelve-Pulse Gate Multiplexer block routes gate voltage signals to the 12 switching devices in a Three-Level Converter (Three-Phase) block. The block multiplexes the 12 gate signals into a single vector. Gate signals are ordered as a-phase, b-phase, and then c-phase, with four gate signals per phase.

When you switch the block inputs to electrical ports, the block shows 12 pairs of electrical connections, each pair corresponding to the gate and cathode of a switching device.

Ports associated with the gate terminals of the Three-Level Converter (Three-Phase)a-phase switching devices. You can set the ports to either physical signal or electrical ports.

Ports associated with the gate terminals of the Three-Level Converter (Three-Phase)b-phase switching devices. You can set the ports to either physical signal or electrical ports.

Ports associated with the gate terminals of the Three-Level Converter (Three-Phase)c-phase switching devices. You can set the ports to either physical signal or electrical ports.

Vector output port associated with the multiplexed gate signals. Connect this port to the G port of the Three-Level Converter (Three-Phase) block.

Electrical conserving ports associated with the individual cathode terminals corresponding to the Three-Level Converter (Three-Phase) block a-phase switching devices.

Dependencies

These ports are visible only when you set the input ports of the Twelve-Pulse Gate Multiplexer block to electrical ports.

Torque Control in Three-Level Converter-Fed Asynchronous Machine Drive

Control the torque in an asynchronous machine (ASM) based electrical-traction drive. A high-voltage battery feeds the ASM through a three-phase three-level neutral-point clamped controlled converter. The ASM operates in both motoring and generating modes. An ideal angular velocity source provides the load. The Control subsystem uses the field-oriented control strategy to control the flux and torque. The current control is PI-based. A proportional controller regulates the neutral point voltage. The simulation uses several torque steps in both motor and generator modes. The Scopes subsystem contains scopes that allow you to see the simulation results.
