DC Fast Charger (30KW) Design & Development

We are seeking a skilled engineer to design and develop a 30 KW DC fast charger based on the Infineon /OnSemi/ Microchip SiC module reference design.. The inverter will need to handle power ratings between 10 kW to 50 kW.

Ideal Skills & Experience:

- Background in power electronics

- Proven track record in inverter/fast charger design

- Experience in industrial applications and CANBus protocol

- Ability to design for power ratings between 10 kW to 50 kW

We are seeking a skilled engineer to design and develop a 30 KW DC fast charger based on the Infineon SiC module reference design. The ideal candidate will have experience in power electronics and familiarity with high-efficiency charging technologies. Your expertise will be crucial in ensuring the charger meets performance and safety standards. Please provide examples of previous projects and any relevant certifications.
