Precharge circuit design considerations
Hi,
how precharge circuits are used in industrial for high voltage applications? please explain how to design precharge circuits, what are the parameters to be taken into consideration for designing precharge circuit??
thanks
Sorry, i didn't understand what you are explaining. I want to have over current protection by sensing the current using a resistor and by using the voltage drop across the Rsense, we can do over current protection of the circuit. But i want to have the precharge circuit also, so i am getting...
Load can be a motor/charger with high current.
I was not given any precharge time, i am new to these precharge/OC protection circuits. So can you please take an example of a standard circuit for Over current protection and precharge so that i can derive what is my requirements are to be..
current limit : 100A
Precharge time: 1usec
Protection type : fuse type
Source : DC voltage 48V
Load : capacitive
Inrush current : 240A
My precharge circuit should be on for 1usec initially when the board is powered on, after that precharge circuit has to be bypassed, allowing the OC protection...
I don't have any critical specifications for timings. Let us take 1us for now.
I need precharge and overcurrent protection circuits to protect my load.
For initial power on time, I have to use precharge circuit to limit the inrush current and after that we have to bypass the precharge circuit...
i need precharge/predischarge circuit to limit the inrush current that occurs when the board is powered on initially. 100A is the max rate current for OC protection
Thanks for ur texts..
My pcb size has been restricted in size so It's becoming difficult for me giving RF tracks on top layer, so it's forcng me towards one more inner layer for RF routing.
Please tell if u have any experience regarding losses and any other considerations to be taken care in...
Hello,
Can we design a Multi layer RF pcb, does it work actually?
I want to see the performance of RF multilayer pcb, please share if you have any references regarding this.
Thanks in adv.
