Case Study: VONSCH achieves one-year faster solar inverter and battery charger development with MathWorks Model-Based Design (MATLAB & Simulink)

VONSCH Speeds the Development of Control Systems for Solar Inverters and Battery Chargers

VONSCH, a developer of solar inverters and battery chargers (FOTO CONTROL 1f and FOTO CHARGER), faced rapidly changing legislation and a move to more custom, single‑phase products that made traditional C‑based, hardware‑first development too slow. To accelerate development and enable early validation before prototype hardware existed, VONSCH adopted MathWorks’ Model‑Based Design approach using MATLAB, Simulink and Simscape Electrical (with Embedded Coder for production code).

Using MathWorks tools, VONSCH modeled electrical plants and controllers, ran closed‑loop simulations, and generated C code for a TI Piccolo microcontroller, refining designs through hardware‑in‑the‑loop testing and spectral analysis in MATLAB. The approach cut product development time from an estimated 18 months to 6 months (saving one year), accelerated R&D via model reuse (about 3× faster), reduced the number of hardware prototypes, and enabled on‑time product releases now in production.
