TIDM-1000: VIENNA

Part Number: TIDM-1000

Hi Team,

Does DC-link voltage must be larger than 2*√2*AC RMS voltage?

My customer found this on https://unitedsic.com/fet-jet/ Vienna's part. He want to know if this reference design needs to respect this rule.

Thanks & Regards

Hi Yale,

The minimum voltage should be decided by the three phase bridge rectifier assuming the boost stage is not taking effect.

Hi Chen,

1. According to the TI's program, in build2, the current loop cannot control the bus voltage, and the bus voltage cannot be stabilized at 400V.

2. The power is only 800W. Does the 1200W provided by TI meet the condition of a load of 200 ohms?

Thanks & Regards

Yale

Hi Yale,

Looks like you and Katherine is asking the same issue. I think we have tested different load conditions for efficiency test. Will see how Katherine reply in another thread.

Regards,

Chen
