I designed a DAB Converter but I don't achieve ZVS (zero-voltage switching). Does it have something to do with my control set-up. Or the circuit parameters?
I am not familiar with a "DAB" converter. What does "DAB" mean in actual words??? And Zero Voltage switching is usually part of an actual circuit, not a block diagram. Really, there is no information in that block diagram that will help me answer the question.
Thank you for your reply. What I meant by DAB was Dual-Active Bridge Converter. I am aware that ZVS is part of the circuit. However, I was just wondering whether it has something to do with the control which prevents it from happening.
OK, and thanks! I am not used to proceeding from that point of view and with that terminology, and thus none of it was clear to me.
If the "active bridge is the same as what I see called "an H bridge", then zero voltage switching would seem to demand a resonant condition, or a forced effective resonant condition. Both presenting quite a few challenges.
