Hi,

please, can you tell about the number of IGBT transistors with low cost.
I need them to use them in a 4-Quadrant Chopper to use it in a DC motror speed control.
the Nominal voltage source is 40 volt Max for the motor.

Thank you,

Hobby or commercial?

I've had excellent luck with eBay for hobby components.

What is your expected peak current?

Would you please specify what you consider low cost. Are you going to buy a few or will there be a volume order. If you have a relationship with a distributor ask for samples. Free is as good as it gets.

Hi,

My expected peak current is 10Amp

The cost has a range (5 - 10) $If you have any model number of the IGBT's, please reply #### Papabravo Joined Feb 24, 2006 15,525 Originally posted by Kh_genius@Apr 4 2006, 06:39 AM My expected peak current is 10Amp The cost has a range (5 - 10)$

How hard did you try to find these parts? A two click query to DigiKey produced

10A Part
Fairchild ISL9V2040 cut-tape $1.78, bulk$1.90

15A Part (you do want some margin right?)
OnSemi MPG15N40 bulk, $2.70 OnSemi NGD15N41 cut-tape,$1.84

Where do I send my bill for purchasing services? I'd say less than half your minimum price was a good days work, eh? (Just kidding about the bill part, but my wife makes big bucks as a purchasing manager; she does this stuff day in and day out)
