A 24 VDC, 10 A AC/DC converter design has been done using the eDesignSuite on the ST website.
The converter gives a very stable output at 24 VDC. We did not encounter any problems when we used the converter at normal loads below 10 A.
However, when we connect loads whose normal driving current is below 10 A but transient period current is above 10 A to the output of the converter, the converter protected itself by cutting off the output current. For example, when we tried to drive two LED bulbs together, with a normal driving current of 2.5 A and a startup transient period current of around 8 A, the converter cut off the output current and protected itself. At this point, our expectation is that the converter can tolerate short-term transient currents greater than 10 A.
Although it is an excellent feature that the converter we manufactured using ST eDesignSuite protects itself by cutting off the output current at 10 A, this situation becomes a problem for loads with transient period current greater than 10 A.
We have the following questions on the subject:
Thanks in advance.

Hi @sonerA ,
thanks a lot for your interest in eDesignSuite. I am forwarding your question to the application engineer responsible for this kind of design. I'll let you know the answer as soon as possible.
Best regards,
Patrizia
