Hi Anand1,

What controller are you planning to use? 

It is actually only differs with rectification, but from bulk input it is no different from single phase design.  Thanks.

The power is approximately 12 watts per phase for a total of 36 watts. The load would be balanced. Can I use 6 diodes to rectify and then use one pf correction circuit or should I use three power phase correction circuits. I dont have a neutral in this circuit.

I dont have a controller picked but I am open to recommendation. Thanks!

Hi Anand1,

Yes you just need 3 phase input rectifier for the input then you just need one PF controller after the rectified AC.  What is your power factor requirement?  I guess you need isolation?  Can you give me your specifications (Input Voltage range, PF requirement, CV/CC?, application?, etc) so that I can suggest you controller for your application.  

Sorry for late reply, we just had log-in problem.  Thanks.

The input is 3 phase 115 VAC@400 Hz Y. The rectified output goes to another circuit which has isolation on it. The power draw would be no more than 50 watts. PF has to be close to 1.0. Please let me know if you need any additional information. Thanks!

Hi Anand1,

What is your exact application for such design? We would like to know so that we can recommend proper Power Integrations product as per specification and application. Thank you very much.
