We have the expertise to design custom power electronics, as well as the equipment and facilities to test them. In addition, our EMC pre-certification laboratory enables us to iterate quickly and efficiently throughout all design phases in order to reduce the risks associated with bringing products to market.
We offer custom solutions for inverters, battery chargers, motor controllers (drives), LED controllers, solar controllers, as well as all applications involving AC-DC, DC-DC, DC-AC, and AC-AC converters.
Our typical design process:
- Development of the specifications
- Preliminary research into a power architecture that meets the requirements
- Component selection and preliminary system design
- Ideal simulation (PSIM software)
- Simulation with actual transistors (PSIM software)
- Refinement of the control loop by integrating the embedded controller (PSIM software)
- Processor selection and detailed system design
- Purchase of initial prototypes
- Commissioning and preliminary EMC testing. Embedded development of software essential for testing.
- Circuit adjustments
- Remaining embedded software development
- Delivery of documentation and knowledge transfer
- Support provided for as long as the product is on the market
