UCC2813-0-Q1: Boost converter solution

Part Number: UCC2813-0-Q1
Other Parts Discussed in Thread: UCC28C40-Q1, , UCC28951-Q1

Dears,

I'm looking for the best solutions of automotive application's high power boost converter. But It is not easy to find that solutions. Could you recommend it for me? The requirements are as follows.

Input voltage : 240V(dc) to 420V(dc), Output voltage : 420V(dc), Po=3.5kW

I'm considering the PWM controllers of UCC2813-0-Q1 and UCC28C40-Q1. Please share the best solutions and related document with me.

Regards,

Jeffrey

    Hi Jeffrey! 

    Thanks for getting in touch! I recommend taking a look at this reference design, it has similar power levels to what you've specified above. Some tips for designing high power boost converters can also be found here if you'd prefer that topology. 

    Thank you again for reaching out to us, I hope this information helps you with your design!

    Hi Aidan,

    Your recommended solution is very heavy and complicated. I'm looking for simple converter solution. As I told you, I'm considering the PWM controllers of UCC2813-0-Q1 and UCC28C40-Q1. I want to know that they can be a good solution or not. If not, could you recommend the simple converter solutions?

    Regards, Jeffrey

    Hi Jeffrey! 

    The short answer is that these devices are generally geared towards lower power applications and will not work here. A recommendation I received from one of our power experts is this reference design. This is also not a very simple solution, but it has some valuable insights on choosing components for a system with this power level. If a boost topology is important, you will most likely need to design multiple phases to reach the desired power levels without unrealistic components. One way you could proceed is with a phase shifted full bridge design. It is more complex than just a boost, but it handles power levels like yours very well. Here is an automotive PSFB reference design using the UCC28951-Q1 that would be a good starting point if you choose to go that route. 

    Thanks again for getting in touch, I hope this information helps!
