Our Engineering Department is composed of designers in electronics, mechanics, electrical engineering, and control systems. We use the following software to develop our products:
For mechanical design and layout of PCB :
Creo Elements Pro for mechanical design, Orcad for PCB schematics, Allegro for PCB routing.
The mechanical assembly (integration) can be adapted if necessary to the specifications of our customers.
For software :
Sourcery Code bench (STM32-µC), Code Composer (DSP-F2812), Altera Quartus, Model Sim (FPGA Cyclone 3), Visual Studio et Lab View for the IHM.
For power electronics design :
PSIM for simulations of the power and control boards, LT SPICE for electronic board simulations
Buildings, test area and testing equipment
Sigmaphi Electronics has all the assembly and wiring equipment in-house to manufacture modules that will be pre-tested before being integrated into racks.
Once equipment is fully assembled, it is tested according to a standard test protocol or adapted to customer’s needs.
Once equipment has been tested, it is shipped and can also be installed at the customer site, if requested.
The company moved to new buildings of 4000m² in 2014 located in Haguenau – France.
Some assembling stations
We have the necessary infrastructure and measurement equipment to test up to 7 systems simultaneously.
The building is equipped with a 1 MVA power transformer, which gives us the possibility to simultaneously test a large number of systems.
Equipement of our test area :
All workstations in our testing area have :
• 400 V, 750 – 1000 KVA three-phase current distribution with voltage and current display for each step.
• 690 V, 300 KVA three-phase current distribution, with voltage and current display for each phase
• A three-phase current distribution with variable voltage from 0 to 480V300 KVA, with voltage and current display for each phase
