Development time for implementing Gejian solutions varies based on application complexity and your team's experience. Typical timelines are: For standard motor drive applications using our reference designs, initial prototypes can be developed in 4-8 weeks. Full product development including optimization and testing typically takes 3-6 months. For EV traction inverters, development time is typically 6-12 months due to higher complexity and safety requirements. Using our evaluation kits can accelerate initial prototyping to 2-4 weeks. Our reference designs are proven and can significantly reduce development time compared to starting from scratch. The integrated solutions (like IPMs) can further reduce development time by simplifying the power stage design. Our FAE support throughout the development process helps avoid common pitfalls and accelerates time-to-market.

Use our evaluation kits and reference designs to accelerate development. Contact our FAE team for project planning support.

We offer multiple ways to evaluate Gejian solutions before committing to a full design: Evaluation kits are available for our major solution offerings, including complete hardware and software for testing. These kits allow you to evaluate performance, efficiency, and thermal characteristics in your specific application conditions. Reference designs can be reviewed to understand the implementation approach and component selection. Our FAE team can provide detailed technical presentations and answer specific questions about solution capabilities. For high-volume applications, we can arrange samples and provide application-specific testing support. We can also provide simulation models (SPICE, thermal) for preliminary evaluation in your system simulation environment. Contact our sales team to request evaluation kits or samples for your application.
