Hello any and all I'm new to the site and hope someone here can help me. I am tired of buying boost converters that fail the ones I'm talking about are the 150w DC-DC converters that you c on Ebay. They short pretty easily so instead of waiting 10 days to get more and take chance it does same thing thinking to make my own. A very simple and cheap DC-DC boost converter I have 1x diode 1N1007, a 10uf 315v capacitor, a transformer I want to use a SW7N60 where the switch is to rapidly open and close to charge the capacitor and boost the voltage. Just not sure how to wire I need to supply constant 30vdc to LED. 9vdc battery and button makes a 100w LED light up just need the transistor to work it and also not to exceed voltage rating any and all help is welcome. Thanks

A 1N4007 is very slow. It was designed to work at 60hz. It will not be happy working at switching power supply speeds.
I think you need to order parts any whay.

Next: What LED are you using? I think you should get a LED power supply not a 30vdc power supply. They are on ebay also.
A power supply for 100W, 30V, 3.3A for LEDs will regulate at 3.3A not 30V. LEDs are current not voltage devices.

I agree a driver would be the best way to go but since the LED is only a cheap 30w COB or a 100w driven with a 12vdc Walwart and a 150v dc-dc converter for my indoor pepper garden been working pretty good I just through things together around the house and because things break I'd like to know how they work so I can repair if needed that's why I'd like to build. I used this guy's example of learning about conductors made this simple device that works

but just need to regulate the power with a switching transistor to turn on and off could not that work and be cost effective?
