Simulation Software for Power Electronics
PLECS® is the tool of choice for high-speed simulations of power electronic systems. It is available in two editions: PLECS Blockset for seamless integration with MATLAB®/Simulink®, and PLECS Standalone, a completely independent product.
What's New in Version 4.4
- Code Generation for Multi-tasking Systems
The PLECS Coder has been enhanced with the capability to generate code for multi-tasking systems.
- Enhanced User Interface
The Scope and the XY-Plot let you display a legend on top of the plots for easier identification of signals without having to show the data widget. Subsystems can now be easily converted to configurable subsystems.
- New Library Components
The component library has been extended with a From File block, continuous and discrete PID controllers, continuous and discrete filters and new power modules such as the 3-Level Half Bridge (T-Type).
- And More
Please see the Release Notes for more new features.
Application example: HIL simulation of MMC
The PLECS RT Box is a modern real-time simulator that can be programmed and operated from PLECS. With its 32 analog and 64 digital input/output channels and its 1 GHz dual-core CPU it is a versatile processing unit for both real-time hardware-in-the-loop (HIL) testing and rapid control prototyping.
The arrangement above is used for real-time simulation of a grid-connected modular multi-level converter (MMC) with four interconnected RT Boxes. Each phase leg of the MMC consisting of 10 half-bridges has its own slave controller and is simulated on a separate RT Box. The fourth box at the top simulates the passive filters and the grid. The RT Boxes are interconnected via high-speed serial links on the back to exchange simulation data and synchronize the simulation step. All boxes run with a time step of 3 μs.
The controls are implemented on four C2000 microcontrollers, which are connected to the front of each RT Box via LaunchPad Interface boards. The master controller at the top communicates with the slave controllers via an SPI bus.
