IRFS641 – Improved inductive ruggedness

May 1, 2 0. After they were in, still nothing. Mar 4, Mar 3, Do you already have an account?

Load Output Sample Rotor 0 kw vac Aug 17, 5 1. I’ve redrawn the schematics to better understand the circuit topology. You May Also Like: For now, I’ll try this emergency solution as I need to use the generator this weekend. I do some checking, and the Darlington I put in was sorted, as was one of the BJt’s again.

Data sheet for the following components

The only components I hadn’t replaced were the resistors at R and R5. Sep 3, 5 0. I Jumped the 12v across the exciter brushes and got 30vac momentarily at the power outlets. I really don’t think the AVR is regulating properly though, at 1kw the output voltage is dropping to a bit below vac and 2kw vac. Jul 19, Generator Automatic Voltage Regulator Posted by debe in forum: As you can see, it’s basically a buck converter where the output inductor acts as a load, too.

That way, you could switch the Mosfet way more efficient, use a much higher switching frequency and have a better output voltage regulation.

Can i use mosfet irf to replace irfs Discussion in ‘ The Projects Forum ‘ started by dmechanicJan 14, Jul 17, What do you mean by inductor? Automatic Voltage Regulator Posted by preye in forum: Back to no power.

In this case what IS the role of C2 R2 between bjt base and negative brush? So I opted to replace them. I jumped across the brushes and dataheet power, only it was volts The BJT and the Darlington transistor were toast.

I calculate about 5. Now I am getting like 2VAC at the outlets.

Mostly because i forgot to order them. IRF should work though the Id rating is only 10Amps.

No, create an account now. I just can’t get the darn AVR thing right. After check datasheet of 2n, frequency is very low Transition Frequency ft: You might put a reverse biased diode datssheet the BJT base-emitter terminals to avoid any collector-base voltage greater than 10V D2 zenner then any regular small signal BJT could do the job you don’t need a V rated one.
