have you seen the size of the wire in the fuse?
Will skinny-leg diode restrict amperage compared to fat-leg bridge rectifier?
Hi All,
I want to do some modifications to my power amplifier, to see if i can hear an improvement in sound...but have come across a potential issue.
I want to replace the main bridge rectifier with zero recovery time SiC diodes.
I have a fear that if i replace the fat-legged bridge rectifier (Image 1 below), with a Cree SiC diode assembly, like in Image 2 below, that the skinny legs of the Cree diodes will restrict amperage, even though the Cree diodes are rated at the same amperage as the fat-legged bridge rectifier.
What's your peoples take on this?
Image 1 - fat legged bridge rectifier
Image 2 - skinny legged Cree diode assembly

@erik_squires good point, thanks! looks like I will now go ahead with my plan! |
The 'fat legs' are for mechanical connections to the rectifier, either quick connects or soldering, and do not reflect current carrying capacity. If the diameter of the Cree assembly leads is 1mm or more they will easily carry up to 35 amps. Diodes do not carry steady state current, they only pass 1/2 cycle or else they'd melt. |
Why a correct rated fuse blow at start-up? Think about it! It blown because it cannot stand the inrush current! Does it also restrict/limiting the current flow and dynamic??? |
