I want to clarify something that I read on the internet.
"FETs degrades if used as a D.C blocker."
Is it a valid statement?
Does it also mean that MOSFETs also degrade if used as a switch to control D.C current?
I don't believe it but just wanted to clarify it.
I am trying to build a simple DC to DC boost converter.
I am concerned with the body diode of the MOSFET (IRFZ44N) used as a switch.
How can I make sure that the body diode does not conduct when the inductor kicks?
The objective is to make the schottky diode conduct to charge up the capacitor...
I was hoping for a diode to prevent reverse feeding but according to FvM, it is missing.
Do you mean USB buses (US buses)?
I think the second USB connector with each screen is only extending the +5 V and GND.
I mean that this PC can provide 1.5 A through 4 USB ports collectively. If it were a normal PC, I would get 2 A from 4 USB ports.
But this an embedded PC with limited power supply and I do not want to stress it.
Yes, your diagram is correct. It means that I will draw 1 A from 2 USB ports from...
No, there are two screens. Each one with two USB connectors so that 1 A can be drawn through two USB ports.
Thus two screens need to draw 2 A from the PC; 0.5 A more than it's power supply can handle.
Thus I want to connect the second connector of each screen to an external hub with external...
It seems that you need critical timing and high frequency pulses.
The better option is not to rely on operating system for timing. If you are using Windows, it is going to be a problem as it is not a real time system.
Thus, your software may stop executing and produce longer pulses for a while...
I have to power two touch screens using an embedded PC. The PC can provide 1.5 A maximum through USB ports.
Each screens takes 1 A of current from USB. Thus, there are two USB connectors (in parallel) with each screen.
Overall demand from two screens is 2 A that cannot be handled by the...
I think, your fan does not draw a huge amount of current. You can simply insert a variable resistor in series of the fan supply. That will slow down the fan.
It is nearly a 5 year old thread. I remember when I had noise problems. But once again, I am combating noise in my new PC unit. I have...
I want to create virtual folders in a network so that I can move them between servers while keeping the access paths the same.
I have tried with IIS to create a virtual folder but the path is like: \\servername\virtualfoldername
If I move the folder, the servername needs to be changed. I want...
Such an old thread!
I have not yet decided to make it open source.
Nevertheless, I can share the compiled version (though it has some problems).
I have to dig in my code to finalize it and then create an installer.
Regards.
I am getting 1 ring (METAL1) across the capacitor which has been connected to gnd!
Your answer for vdd! connection to the ring is still not clear to me.
Is it either gnd! or vdd! or both connections at the same time to the ring?
The latch-up problem has been fixed as a group member had added...
Connections to vdd! and gnd! can be ignored according to the supervisor.
Can you tell me how can I connect vdd! to guard rings of the capacitors?
I mean which via to use?
And I will add more bulk connections as suggested.
Regards.
