Wait, I thought that current mode control (hybrid hysteresis control) was only possible in half bridge topologies? And not applicable in full bridges? Which would suggest if controllability is the biggest issue this would be chosen.
There is also a possibility of paralleling two half bridges...
Okay, roger that. However, if the turns ratio increases in the half-bridge, how does the number of secondary turns stay the same? Surely it should have to increase so that the extra voltage is induced in the secondary? Otherwise double the number of primary turns needs to be present, but then...
Hello,
Thank you for your suggestion. Do you mind me asking though, why would you choose a half bridge inverter? The transformers turn ratio will have to double, because the half bridge chops the input voltage to half its initial value, whereas in a full bridge it is chopped but remains at the...
Hi! Maximum output is 5kV, at 150mA.
I didn’t know that about current mode control of half bridge, that it was different to full. But yes, obviously not the maximum power density ever but the highest possible for my application with that criteria placed as the most important. I thought maybe...
Hello,
I have seen a few posts on here regarding whether the full bridge or half bridge circuit topology is best within a SMPS. However, not in regards to power density.
I am designing a power supply that requires a high step up (of 1:20) and must achieve the highest possible power density...
Hello FvM,
The power level is approximately 650W. The issue with the LLC converter from my point of view is that my converter has two outputs both in the kV range. I've never really seen an LLC converter at this voltage level, and since it doesn't take into account the high parasitic...
Hello all,
I am designing an isolated high voltage power supply with the aims of reducing the overall system size and weight, increasing power density. This is leading me to find converter topologies which are capable of operating at high frequencies efficiently. I have been studying the series...
