C2000-3P-SEARCH: Vienna Rectifier, Three Phase Power Factor Correction (3 Ph PFC) Design

Souheil Slim
Prodigy 70 points
Part Number: C2000-3P-SEARCH
Other Parts Discussed in Thread: TIDM-1000, TIDA-010054

I'm looking to use Texas Instruments Three Phase PFC (Vienna Rectifier) to design a 3 Ph 115Vac Line-Line/60Hz input converter with 28V/200A 5.6kW output.

 
Questions:

1- Is the Vienna rectifier able to draw a balanced current from the 3 Ph source to within 3%.

2- Which element in the Vienna rectifier circuit affects the 3 Ph source current balance.

3- What is the recommended optimum output voltage of the Three Phase PFC (Vienna Rectifier) when operating with 3 Ph source 115Vac Line-Line/60Hz .

4- After the Three Phase PFC (Vienna Rectifier) what TI recommends to be able to implement a Dual Active Bridge DC-DC to achieve a 28V 200A output (isolated output).
 
5 - Could you refer us to some useful TI design tools, calculators, circuit simulators /documentations for our application other than the TIDM-1000.

6- Which TI controller is recommended for such application other than C2000 microcontrollers.


Kind regards.

Mr. Slim, P.Eng.

    Hi,

    We don't have an exact number measuring the current unbalance. But normally the unbalance is very minor.

    We have not done much research on this.

    You may try 600V.  However, we recommend to test the condition we suggested in the spec of the user guide

    We have a DAB design https://www.ti.com/tool/TIDA-010054

    Also there is a CLLLC reference design for your reference https://www.ti.com/tool/TIDM-02002

    Please download digital power sdk here https://www.ti.com/tool/C2000WARE-DIGITALPOWER-SDK

    You can find more information related to the reference design mentioned above.

    I think C2000 MCU is a good fit for this kind of application. 

    You can use F28004x/f2837x/f2838x for TIDM-10000, use f28004x/f28003x for TIDA-010054
