CCS: Control Card

Gowthamraj,

              Where is this "beep" sound coming from? There is no beeper on this card. Please provide more information on exactly what you are attempting to do and what you are observing and where.

Hi Gowthamraj,

Are you sure the sound is coming from the controlcard or the power stage? Could you please explain more on what condition you see the issue? running the vienna rectifier? or after connecting the controlcard and writing the program? 

Regards,

Hi sir,

After Connecting the control card and writing the program, the beep sound is coming. And also, the Vienna Rectifier is rated for less than 5% THD at the input source side. But i am not able to get the THD less than 5%. i have no idea which program i have to write to the control card. can you please help me to fix the above mentioned issue.

Thank you

Gowthamraj,

 You have still not clarified where that beep sound is coming from. What is generating that sound?

Hi,

Just want to check back if this issue is resolved?

Hi 

When i do the program for the controller, the beep sound is coming in the Vienna Rectifier kit. It is coming near Capacitor in the output side.

Can you please help me to fix the issue in the Vienna Rectifier.

Hi,

Sorry for the late reply.

Is your vienna rectifier running normally when your heard the sound?

Are you running our reference design code with the TIDM-1000 board?

Gowthamraj,

Perhaps you could attach  a short video of that beep sound.
