Can i use mosfet irf to replace irfs IRF should work though the Id rating is only 10Amps. So I opted to replace them. Sep 3, 5 0. When i got it, it was not producing power.

Honda Generator Automatic Voltage Regulator

I read somewhere about re-magnetizing the exciter with 12V, So i did. The four basic DC-DC converters considered for analysis are the following: Now I am getting like 2VAC at the outlets.


While they do appear to be okay on the outside, with a minimal mark on one of them, they all test OK and are within range for their values. Discussion in ‘ The Projects Forum ‘ started by dmechanicJan 14, It is actually the Mosfet “load”. The motor also appears to be struggling at 2kw even though It is a 6. Mar 4, I calculate about 5.


Jul 17, Generator Automatic Voltage Regulator Posted by debe in forum: Oct 24, Jul 3, 11 0. I really don’t think the AVR is regulating properly though, at 1kw the output voltage is dropping to a bit irfs604 vac and 2kw vac. Mostly because i forgot to order them. Jan 30, 13 4. Rotor winding or feed winding? In this case what IS the role of C2 R2 between bjt base and negative brush?

Jul 19, Mar 27, The BJT and the Darlington transistor were toast. May 1, 2 0. Load Output Sample Rotor 0 kw vac So I bough virtually all the components to rebuild the entire datashest based on the schematic on pg1 as well as the some recommendations for a different Varistor at S2. Jun 25, Stupid question but i want to understand.

And a 2n to replace 2n For now, I’ll try this emergency solution as I need to use the generator this weekend. No, create an account now.

Automatic Voltage Regulator Posted by preye in forum: I will, however, check the sampling voltage and rotor slip ring voltage against load next. Aug 17, 5 1. I Jumped the 12v across the exciter brushes and got 30vac momentarily at the power outlets.

Back to no power.
