The transformer I'm asking about has a 150 VDC working voltage, and so it is rated at 0 frequency. I should have specified the working voltage was DC, and maybe that changes my question for you?
Is this the voltage that can exist across a single winding of the transformer, where it would be dependent on the lacquer or winding insulation? This is different than isolation voltage between primary and secondary windings.
I would like to understand the flaws to my approach in the schematic.
In a SPICE simulation, I simplified the ultrasonic transducer with a 2nF capacitor model.
The USTX Bridge signals will have deadtime between switches.
I notice losses in the simulator which is why I have come here to...
Both are lethal! It takes surprisingly little current to be dangerous . . it is a matter of where it is touched on/in the body and where it must travel through. In your examples, it won't matter where they touch because both are potentially lethal . . don't ever expose your body to that much...
Oh my, you are right. Sorry for flopping my question so badly!
This is the part I'm using actually:

I came to a value of 450uH, considering 70 VAC as minimum input and max load on output as 18V and 1.5Amps. That should give me a minimum switching...
I am now finding that I should not use the minimum switching frequency of 4khz, but instead choose a switching frequency minimum that will size the inductor for me. But I still think it is correct that my switching frequency minimum must be used for max load and max current draw (Vin min).
I would like to use an offline PFC flyback controller that operates in critical/boundary conduction mode.

I am stuck in trying to figure out what my magnetizing inductance Lm for my flyback transformer should be! The datasheet only recommends...
My questions are
1. A CCM operation implies constant current draw. So how can a CCM PFC work when there is no load? What about for very low loads where it forces the inductor to have discontinuous current in it?
2. How does this impact my PFC boost inductor selection? Should I need a...
So this sounds contradictory to what schmitt trigger commented about chokes (other than the current-compensation thing, which I will take as advice from both of you to not use this particular choke part).
Thanks for the reply.
I did not arbitrarily choose my inductance value and specs. I have been using datasheets, app notes, and text references to double check, triple check, etc. that I am choosing the right inductance and current characteristics for what I want to do. I will have about a...
Hello, be prepared for a lot of naive questions.
I'd like to use a "choke" inductor as my conversion inductor (as opposed to EMI filter) in a boost PFC design. I've never made a boost PFC converter before, so I am unsure if I'm making the right choice with this inductor.
My PFC will take...
Interesting.
The reason I ask is of course because I'd like to use an off the shelf transformer for a forward converter. I see that cooper bussman and coiltronics offer these configurable windings parts (hexapath, versapac) and they give examples for use both in a flyback and a forward mode...
This is possibly a stupid question, but is it possible to use a flyback transformer as a forward converter transformer? It seems like a reset winding is an optional method for resetting the core for forward converters, so could I use a flyback and reset the core a different way and be fine with...
