Product Recommendation for Inverter with Access to Reference Signal

Carol Mikhael

Hello everyone,

For my research, we are looking for a single-phase inverter demo/evaluation board (sine wave output if possible) that allows us to inject our own reference signal and/or interact with the PWM signal of the inverter. The reference signal will operate in the 40-80 Hz range.

We think that a demo/eval board may work best for our research. What would demo/eval board would you recommend?

Thanks for your help!

Hi Carol,

Have a look at these kits:

www.ti.com/.../TMDSHV1PHINVKIT
and
www.ti.com/.../TIDM-SOLAR-ONEPHINV

Do check the documentation for further details.

Regards,
Gautam

Thank you for your suggestions.

Would these allow for a signal to be directly connected as the reference signal? It seems like the PWM here is created by software using a chip.
Is there a design that would allow for a signal coming from an external source to be directly inputted, maybe through a pin or jumper, without the need for a ADC possibly?

Thank you again.

In the BOOSTXL-BUCK design, I made it so I can either use the ADC or a signal brought in through the SPI interface for the feedback path.
Also, the HV_1PH_DCAC can use either the ADC or SDFM. There is also a gridconnectedinvlcfltr version that I am less familiar with.
