Even if you use it for commercial use, there is no problem when say it.
Let me know if you still need help.
1. what is the time delay in seconds required for bypassing the inrush current limiting resistors in sg3525 circuit.
At least you need 3 seconds, then start SG3525
2. which output of the sg3525 gives the first ouput pulse
It should be output A
Hi MicrosiM ,
Thank you for the clarification.
In the 1Kw circuit if the output A of sg3525 is given to Low In of IR2110 , on the first pulse itself the bootstrap capacitor of IR2110 will get charged. so that there will be sufficient voltage accross the boot stap capacitor when the pulse at The Hin of IR2110 arrives.

What does that supposed to mean in reality?
Hi MicrosiM ,
I was comparing Ludos ver2 pcb and ver3 pcb, interchanging SG3525 output pin avoids 3 jumpers in ver2 pcb.
This can be done if you keep both the Ic as per ver2 layout and integrating it to ver3 pcb keeping Mosfets and Transformer as it is.
It makes a symmetrical nice layout

specs of your servo?
