2N3055 FLYBACK DRIVER DOWNLOAD

It sounds like your PSU is shutting down due to overcurrent. Also, I think my flyback is done for… The high voltage negative pin started arcing to the one next to it. Is it a flyback? This is a low current high voltage power supply, what kind of lamp do you want to supply from such a high voltage? The driver is built on a piece of vero board with multiply resistors to obtain the needed wattage rating, this is far from optimal as the load sharing between them is horrible, to ensure better sharing.

What purpose does the small capacitor across the protection diode serve? This site uses Akismet to reduce spam.

August 9, at I worked with several transistors and found that a MJE and similar along with much higher filter cap 50v uf flybsck higher wattage resistors will bring this to a workable level. What kind of transformer are you trying to drive? For the main cap I used a uF Cap.

Thanks for any help! June 19, at What input voltage have you used? I have mine set up with the diode but without the capacitor and it works fine. July 19, at When I do a diode check every possible way I get 0V except for neg to collector and pos to base I get. November 17, at April 24, at Is it a iron core?

If you have any additional questions about the ZVS driver, please ask them in that article and not this for the 2n driver. Okay, I tried more winding combinations, 4—8 primary turns and all the way up to 14 feedback turns. The transistor used in this circuit should not have a voltage rating higher than V, due to the higher base current needed of higher voltage rated transistors, this might in some cases cause problems where the self-resonating circuit can no longer drive the transistor.

I only used a jumper to turn it on in the ATX plug. To find out more, including how to control cookies, see here: Hey Vignesh I do not have any such simulation model. June 16, at What you can do is provide some isolation between the pins with pieces of plastic and super glue. I wonder what material would be more suitable for isolation?

Why would it change all of a sudden unless it had somehow failed internally? November 25, at I have 2 TIP35C transistors and some 2Ns, both of which seem to be working with maybe only minor damages. Notify me of new posts by email.

The circuit now pulls around 3A at 12V. June 8, at
