I calculate about 5.

Quote of the day. As you can see, it’s basically a buck converter where the output inductor acts as a load, too. The BJT and the Darlington transistor were toast.

IRF should work though the Id rating is only 10Amps. After check datasheet of 2n, frequency is very low Transition Frequency ft: Mostly because i forgot to order them.

I just can’t get the darn AVR thing right.

You might put a reverse biased diode across the BJT base-emitter terminals to avoid any collector-base voltage greater than 10V Daatsheet zenner then any regular small signal BJT could do the job you don’t need a V rated one. Mar 4, Yes, my password is: Jul 19, Your name or email address: So I bough ircs640 all the components to rebuild the entire board based on the schematic on pg1 as well as the some recommendations for a different Varistor at S2.


The only components I hadn’t replaced were the resistors at R and R5. Generator Automatic Voltage Regulator Posted by debe in forum: When i got it, it was not producing power. So i KNOW that the coils and exciter are working. Oct 24, Jul 3, 11 0. Aug 17, 5 1.

I’ve redrawn the schematics to better understand the circuit topology. I do some checking, and the Darlington I put in was sorted, as was one of the BJt’s again. Jun 26, Automatic Voltage Regulator Posted by Dumken in forum: Yes, I was talking about rotor winding.

After they were in, still nothing. May 1, 2 0. Back to no power. Rotor winding or feed winding? So I opted to replace irrfs640. Jan 30, 13 4. What do you mean by inductor?


Jun 25, Discussion in ‘ The Projects Forum ‘ started by dmechanicJan 14, Can i use mosfet irf to replace irfs It is actually the Mosfet “load”. I will, however, check datasheef sampling voltage and rotor slip ring voltage against load next. I read somewhere about re-magnetizing the exciter with 12V, So i did.
