Hello ! I consulted Power Integrations about a power supply design using one of their TOPSwitch IC's. The details of my questions are here:
**broken link removed**
I have almost everything figured out, except for the snubber network for the StackFET configuration. This is used to improve the ability of the IC to handle high voltage.
I am definitely not an expert in this kind of circuits, but to me this snubber network shown at
**broken link removed**
... is just a peak clamp because it doesn't use a capacitor in a classic RCD configuration.
ST has a component called PEAK CLAMP in a single package that is very much the circuit proposed plus one single resistor in series, in this case 200 Ohm.
The datasheet for this component is here:
**broken link removed**
I would like to calculate the peak clamp for a tri-phase powered industrial power supply with a bus of 535 VCC, exactly the same circuit as the example below. I have the data for the transformer.
I don't find very easy the way ST suggest its calculation.
Could some friend give me a hand with this particular issue ? I would appreciate that very much.
Best regards to all
