TMS320F280049: TIDM-HV-1PH-DCAC lower input voltage

Hitoshi Sugawara

Part Number: TMS320F280049

Hi Expert,

A customer is looking for the EVM such like TIDM-1PH-DCAC, but DC voltage requires lower than 100V DC.
Could you please let me know the lowest input voltage with TIDM-1PH-DCAC?

Requirements:
Input : 100V DC or lower and 2A or less.
Output: 100V AC or lower. No specific request for output current.

If we have other better TI-Design, please let me know.

Thank you for your kind check.
Best regards,
Hitoshi

with a single inverter stage that this design is, for 100Vac (RMS) they will need a minimum of

100*1.414*1.20 = 170V DC bus.

Othwerwise they may need to go to a two stage solution, with first one being boost.

We do not have an exact solution for this. Closes is the below but it does not have Voltage Mode Control support for the output due to a different topology selection for Grid Tied Inverter.

Hi Manish,

Thank you very much for your prompt check.
Will bring the lowest DC input voltage.
The customer has already looked into http://www.ti.com/tool/TMDSSOLARUINVKIT.

Thank you again.
