PI Expert will not let me enter 300V as output.
I need to build a boosting supply that makes 300v.
Because of the short turn around time and the need for a custom TX, I was going to use a PI part and their rapid prototype service.
PI expert limits the output voltage to 100v.
Can I create my own Tx design?
Please advise.

Thanks Wesley,
I am using a flyback topology to boost. I need to closely manage current.
PIXI seems to assume a fixed number of windings on the primary and only adjusts the number of turns on the secondary side. . It should only be a two times the primary side, but alas.
It always tells me that the reflected voltage is too high.

Hi Will.
What part are you wanting to use, and what is the spec of your project?
The shortest part of the answer it, whatever part gets me there.
I was thinking that I could use the linkZero-LP.
As this part limits me to 3 watts, I would make the output current of the flyback be 10mA. I am not sure how the LinkZero part decides where to hold the current, but I assume that it will simply limit to 3 watts.
Ultimately the application is to charge a cap to 300 volts and hold it there until duty calls. During the beginning of the charge, I expect that the output will not reach 300 until the cap is nearly charged. This is perfectly acceptable.
The ultra caps will not be discharged while the PS is plugged into the AC. (really the UPS does not run until the AC goes away). The flyback will start up again once AC comes back online.
Thanks
Hi.
Currently PIExpert only supports flyback, no boost.
Assuming you want to do a flyback with a 300V output, you could try to use PIXls. This tool will also generate a transformer datasheet similar to PIExpert (you will also get other important parameter like diode peak reverse voltage and so on).
