TIDA-010054: Design Review

Part Number: TIDA-010054

Hi Team

Greetings!

1. The reference design doesn't include the firmware for closed-loop control of the converter which is necessary for EV charging applications.
2. The reference design is for bi-directional power flow however for EV charging applications only unidirectional power flow is required. So in the reference design the output rectifier SIC MOSFETs have to be replaced by high-frequency diodes.
3. Parallel operation of the converter is also required for high-power EV charging applications. Thus we need your support for the development of firmware for closed-loop control of the modified converter. In addition, we need the proper validation of the modified converter design.

Regards

    Hello Arabindo,

    thanks for your mail.

    1) We are currently in progress to put SW examples for the TIDA-010054 on TI.com. Our plan to have this by 28th Sept. After that day you can download the SDK SW examples we have put together as a starting point for your development. Hope this is not too late for you.

    2) yes, the design is bi-directional. We have seen EV-charging applications which require this. It looks like your plan is to use only in uni-directional mode. Yes, for this you can replace the SiC-FETs with SiC diodes. You need to chose based on your requirements.

    3) We have not tested the converter in parallel operation, but it should be possible to do this. The SW-examples that we release after 28th Sept should be a good basis for the modification you plan to do. Validation of your design is in your hands.

    best regards
