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.
Examples
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.
Three-Phase Three-Level PWM Generator
Use the PWM Generator (Three-phase, Three-level) to control a Three-Level Converter. The upper and lower supply voltages are input to a Neutral point controller, which balances the DC-link capacitor voltages. Reference AC waveforms are used as inputs to the PWM Generator. There is one time scope for the controller waveforms.
