- Role
- Embedded development and signal processing
The need
Symmetra PX is Schneider Electric's range of modular three-phase UPS for data centers and critical installations, from 10 to 500 kW depending on the network voltage. To validate the control loops of their power controllers, the team needed a controlled source able to reproduce the conditions of the electrical network on a bench.
The solution
- 01
Low-power inverter, dedicated to testing the controllers' control loops.
- 02
Real-time embedded software for the inverter, in C and C++ on a DSP.
- 03
Control and signal processing algorithms, tuned in MATLAB.
The outcome
Test inverter delivered to the team to validate the range's power controllers on the bench.
