I like this video very much. Such a multi phase inverter inspires to also use this technique for wide output current range tig welding machines, isn't it? However, there seems to be no high voltage switchers in the market. Opinions please.
Hey Fesz. In the last part you say about synchronising separate supplies. I'm curious as to if this can be done if they're producing different output voltages, etc., as the duty cycles may be different? Also, any idea how this works out if one starts to pulse skip?
Of course, there is no issue if the supplies have different duty cycles - in the simulation, the 2 supplies have different output voltages, I changed the feedback resistors. Synchronization will only impact the turn-on moment, nothing else - so the duty cycle is independent of this; with pulse skipping, the supply will simply not trigger on the synchronization input, so that should also work without issues.
Excellent... could you please make video on soft switching topologies
