Best Arduino board for my application

Hi,

I'm an arduino beginner. I would need your opinion on choosing the best arduino for my application.

I need an arduino board to control an Active Rectifier.

The control board that I'm looking for should be able to sampling an input voltage sinusoidal wave with frequency f=85kHz. Then, when this voltage cross to zero, it has to calculate a duty cycle according to a DC output voltage.

The question is: Is there an arduino board with a sufficient clock frequency to perform all these operations?

I've read that ARDUINO 2 is the board with the higher clock frequency fck=84MHz.

Do you think that is it sufficient?

Thank you,

Firenze100.

That's the Arduino Due. You don't translate proper nouns.

The ADC sampling frequency will be:

85KHz * Samples_number_per_period.

The maximum ADC sampling frequency of a DUE is 1Msps, That is to say a maximum of 11 samples per period. I doubt it would be the accuracy you are looking for, wouldn't it ?

You would need a bipolar ADC, it can be done with a DUE providing you add some hardware:

You could trigger an interrupt whenever you cross 3.3V / 2 with the ADC window feature.

Really Thanks ard_newbie, you have been very helpful :wink:
