Hi i update ISD V1.3.0.
- IMC102T-F064

But It is still difficult to use at 110v.
As shown in the picture below, the maximum input voltage range is 220 to 313.46, so it cannot be set.
Is there any other way?

The root cause is that in the configuration wizard, the target DC voltage must be > 1.414 * Max_ Vac.

Refer to the PFC diagram, If we can modify Vout_Ref, we should change the Vout.  We can monitor the VAC, write a script code. Set different Vout_Ref values based on different VAC.

Hi @kkkkjeong 

This error indicates that there is an issue with your voltage parameters.

For PFC output voltage, it should  be >= √2  * MAX VAC.

When maxVac set 220V, the PFC output voltage should be greater than 311V.

The parameter max Vac is not used for protection, it should be a normal working input voltage.

HI  @LinGuohui 
I understand what you mean.
However, in the United States, we are planning to use 110V instead of 220V.
Therefore, the maximum input voltage must be less than 220 volts.
For PFC, we would like to target 190V.

I think the minimum voltage range in the picture should be lower.


Please check the questions I asked in the past and refer to them.

I upgraded my project package, and it's available.

Hi @kkkkjeong 

PFC is actually a boost circuit, which means that the output voltage cannot be less than the input!

So if the max AC input is 220Vrms , The PFC output cannot <= √2  * 220  V.

I don't think this setting is incorrect.

You are right.
But I always said it.
It will be used at 110Vrms.

I upgraded the project package.
And I set it up as shown in the picture.

Therefore, I am operating the product using PFC at 110Vrms.
