TIDM-HV-1PH-DCAC: DC Bus Voltage

Hannah Aaronson

I was wondering if there was a specific reason the DC bus voltage for this reference design is at 380 V? Would it be possible to use a lower DC bus voltage, for example 200 V? If so, would any hardware or firmware changes have to be made?

Thanks!

380 was chosen because control and validation for the final board was done with it.

The design works well at lower bus, with correponding derating applied to Vac,

some of the incremental builds step through a lower bus voltage initially as well.
