What do you mean by voltage mode and current mode?for a voltage mode application, it should not make a difference. If you were going to use current mode, then trailing edge modulation would be required for the current signal to ramp up.
If you are concerned about dead times to eliminate cross conduction, you should let the FET drivers handle that.
My original question was generic as I just wanted to know peoples experiences with both. I gave a specific example of what I'm working on right now that lead to my question, but the question was still generic in nature. I then was able to confirm what DK said about center-aligned reducing EMI, and that it is mostly useful in multi-phase motor applications. Hope that clears up your confusion.Mr RB said:You said you are making a synchronous buck converter, then it turned into multi-phase???
