Library

Open collection of simulation components shared by the other repositories of this project (modelization and control, solid state transformers). Everything is developed in a mixed way — Simscape language, C code, MATLAB code and Simulink — and every component is saved as a Simulink library block, masked, so that it can be dropped into a model like a built-in block.

The same C code that runs inside the models through C-Caller blocks is the code that runs on the target, so control algorithms are simulated and deployed from a single source.

Prerequisites

MATLAB with Simulink, Simscape and Simscape Electrical.

Installation

1. Clone the repository.

2. In MATLAB, add the repository to the path with subfolders.

3. The Simscape components are already compiled: each +package folder in library/foundation has its built <package>_lib.slx next to it. After editing a .ssc file, rebuild it from the folder that contains the +package directory:

   cd library/foundation/<domain>
   ssc_build <package>          % e.g. ssc_build dtt

4. The C-Caller blocks need the C sources. In the model configuration (Simulation Target → Custom Code) add:

   • include directory library/user_defined_functions/ccaller/include
   • the source files listed in library/user_defined_functions/ccaller/all_ccallers.c (that file is a plain list of file names, not compilable C).

Repository layout

Folder	Content
library/foundation	Physical models written in Simscape language (.ssc), grouped by domain: semiconductors, power electronics passives, electrical machines and transformers, batteries, electrochemical, electronics, hydraulics, internal combustion engines, mechanics, control-system examples, varistors, non-linear loads
library/masked_models	Masked Simulink library blocks: converter bridges, modulators, controllers, filters, observers, PLLs, DC links, metering, loads, grid emulators
library/user_defined_functions	The C code called from the models through C-Caller blocks (controllers, observers, PLLs, modulators, filters, state machines), plus two small MATLAB helpers
library/setup_files	The parameter layer: classes and factory functions that build the hardware, machine, device, timing and controller objects used by the model initialization scripts; device datasets and datasheets
library/documentation	Technical notes (LaTeX + PDF) documenting the components: device models, active clamping, crowbars, snubbers, saturable reactors, thermal analyses
library/icons	Block icons used by the masks

Each folder has its own README with a component-by-component description.

Conventions

• Quantities are normalized: *_bez is the peak-per-phase base, *_nom the rated value (line-to-line RMS for voltages, phase RMS for currents), *_norm and *_pu the per-unit value.
• xi / eta are the stationary-frame components used by the sequence controllers.
• Simscape packages are named +<component> and built into <component>_lib.slx.
• C functions come in pairs: a portable core (<name>.c/.h, target-ready) and a C-Caller shim (<name>_simulink.c/.h) that returns a <name>_output_t struct, because a Simulink C-Caller block cannot return more than one value.
• Sources carry an SPDX MIT licence header.
