Hi everyone,
I have a question regarding the choice of wiring material for a push-pull converter . Specifically, I'm curious about the impact on leakage inductance when using litz wire versus foil copper in the transformer.
Could anyone shed some light on whether litz wire or foil copper is...
hi friends,
In STM32F412 microcontroller with HAL Library
I put timer 2 in encoder mode and everything works fine
I want, for example, if the counter reaches 1500, an interruption will occur, but I don't want the counter value to be reset after this interruption.
How can I do this?
I want the...
Thank you, it is an interesting circuit
If we want to make changes so that the battery does not discharge during a power cut, what do you suggest?
Thank
Hello friends
Can the part mentioned in the circuit below be modeled with the help of one or two BJTs?
The culprit of the question is, can the mentioned negative feedback operation be implemented in a simpler way but with the same stability?
We assume that the reference voltage is 0.7
I...
Hello friends
I used the following circuit to make a 48V charger
The problem of this SMPS is that it has different voltage at different temperatures, the changes are about one volt
I understand that the PCB file helps to answer the question, but it is not possible to provide the PCB
How can I...
Thanks Crutschow,
Basically, there is a schematic of this circuit, but I added a diode bridge at the input of the circuit, if I put the diode bridge after the Mega ohm resistors, won't there be a problem?
1698052602
Thanks Klaus
More info added
Yes, no other load is connected to the output of the diode bridge, and for this reason we are also surprised by the random burning of these diodes.
Of course, it burns about 10% of the time
So it doesn't seem like the circuit has a problem, right?
Thanks Brian
It was meant that there is a UPS that we did not connect any laod to its output, we just connected this measuring circuit to its output
I am completely sure that we do not have a problem with the increase or spike of the output voltage
Can harmonics cause this problem? I want to...
Thank you for your attention. M7 is the SMD code written on the Diode
It cannot be repeated for a specific diode D1,D2,D4,D5, random diode burns every time
hi friends
In the diode bridge circuit below, the input voltage is 220 volts, from a modified sine wave UPS (Iron Core)
I used this circuit to Externaly measure the output voltage of the UPS
But there is a problem that M7 diode or 1n4007 SMD burns sometimes, usually it burns when no load is...
hi,
By using IC 74HC14, the problem of multiple interrupts was solved, and in normal mode, multiple interrupts do not occur.
In a noisy environment, an interrupt happens more, we are working on this issue, but the situation is much better than when the IC 74HC04 was used.
Thanks to all the...
In my previous threads, despite the schematics and complete information, they still did not focus on my question and questioned the main question. You can see it in the activity section of my profile.
Please keep the Subject, I will post the test result here and if the problem is not solved, we...
Hi,
Mr. KlausST
Thank you for your kindness and attention, and I'm sorry, I didn't mean to ignore your kindness and help, I really appreciate your honest guidance.
The problem started from where I thought that the difference between the two voltages Vih and Vil in the 74HC04 IC is the...
Mr. Klaus, the circuit is in laboratory mode and without any noise
The input of 74HC04 has a low slew rate and is definitely not a standard logic, that's why I said it is sinusoidal because it is very similar to the input signal. The opto input is connected to an AC voltage of 110 volts with a...
