The fourth box at the top simulates the passive filters and the grid. 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 arrangement above is used for real-time simulation of a grid-connected modular multi-level converter (MMC) with four interconnected RT Boxes. 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 PLECS RT Box is a modern real-time simulator that can be programmed and operated from PLECS. The PLECS Coder now supports non-floating-point signal data types.Īpplication example: HIL simulation of MMC You can also create dynamic dialogs by disabling or hiding a parameter or changing its value depending on the value of another parameter. PLECS now lets you create dynamic mask icons for masked subsystems that change their appearance depending on parameter settings. The new auto-connection feature lets you quickly create connections between two or more components. We have enhanced the schematic editor with a smart routing algorithm that reduces the occurrence of overlapping connections. It is available in two editions: PLECS Blockset for seamless integration with MATLAB®/Simulink®, and PLECS Standalone, a completely independent product. PLECS® is the tool of choice for high-speed simulations of power electronic systems.
