The algorithm R&D prototype SST controller hardware-in-the-loop test platform provides users with a standardized rapid control prototyping (RCP) turnkey solution. Without any low-level hardware development, control algorithms designed in Matlab/Simulink can be deployed directly onto a dedicated prototype controller, realizing the shortest path from “control concept” to “real-time closed-loop verification”, so that engineers can focus entirely on iterating and optimizing core algorithms.

The master/phase-control SST controller hardware-in-the-loop test platform with virtual lower-level control fully virtualizes the control logic of the sub-controllers and integrates it into the simulation model, enabling independent and efficient verification of the SST master/phase controllers. This greatly simplifies the test architecture and accelerates the development and debugging of upper-level control strategies.

The fiber-adapted integrated SST controller hardware-in-the-loop testing solution builds a high-fidelity hardware-in-the-loop test platform for complete SST controller hardware (master, phase and sub-controllers). Its key innovation is the “fiber-adapted” communication architecture, which replaces most of the complex physical I/O wiring with fiber-optic communication, significantly improving integration convenience and test iteration efficiency while ensuring system-level test integrity.

The full-physical-I/O SST controller hardware-in-the-loop testing solution builds a full-physical-I/O hardware-in-the-loop test platform for complete SST controller hardware (master, phase and sub-controllers). It abandons any communication adaptation or conversion and interacts with the controller under test strictly through real physical electrical interfaces, achieving 100% fidelity reproduction at the signal level and providing the ultimate test benchmark for controller performance verification and product finalization.

As systems move toward higher voltage levels and greater power density, the three-level SST — with better harmonic characteristics, lower switch voltage stress and higher overall system efficiency — is a perfect fit for high-capacity, medium/high-voltage solid state transformers and has become an important direction of industry evolution.
