CRD-06600FF065N bi-directional 6.6kW On-Board Charger - how to adjust the AC output?

When operating in DC to AC mode, how do you adjust the AC output voltage?

The reference design is 220V rms output. How to change to 230Vrms ?

Thanks.

    Hello Ian,

    I am sorry to tell you that the AC output voltage is not adjustable by GUI setting. the only way to update it is to modify the code of the controller. Thanks

    Hi @FrankWei - I am re-opening the discussion for more detail. Could you please provide some guidance on what sections of the code and/or hardware would need to be modified for this change to 230V ?

    Hi Ian,

    Could you please advise why do you want to change the output from 220Vac to 230Vac?

    It was a V2L design for our demo. the inverter acts as a voltage source not current source. so it is not able to support V2G operation. If you are familar with C2000 and you do need to modify the output to 230Vac for efficiency measurement or other purposes, you can download the code first. You need to modify the AC output setting and re-program the DSP.

    Resistor load can be used in discharging mode. Please don't connect the OBC to the grid even the output voltage was changed to 230Vac. Thank you.

    Regards,
