i do not agree with, as you clearly see the current path going from the source to the chassis via the capacitor, and then goes from the chassis to the LED's and from the LED's back to the source.

no isolation,
no capacitor in the output side, but i think there is parasitic...
difficult to show all schematic, as we have two separate boards, one for the driver, the other one is for LED board, i am 100% sure there is a closed loop, between input line and LEDs' ( as LEDs are on aluminium PCB) via the 15nF capacitor that connect the line to the chassis, so my problem is...
Hi,
I have a power source that generates 50V/70hz square wave to drive LEDs( there is full bridge rectifier and LED driver), mounted on an FR4, and this drives a LED PCB which is mounted on aluminium PCB, in the input of the circuit there is 15nF between the input and the metal chassis, when...
Re: help about oscilloscope
i think without scope is like makeup without mirror, oscilloscope are used everywhere to have an idea on how reliable and how accurate our electronic is.
i think first we need to check if the noise is it common or differential mode, because based on that we can select the right solution, you can check that by connecting a current probe instead of the LISN and then you measure the noise in one line or in both lines, differential mode can be solved...
Re: Simulation problem of smd BISS0001 ,PIR MOTION DETECTOR IC
i think you don't need to do simulation, it is like microcontroller, you can design your schematic based in the datasheet of the IC
i was not aware that saving the last operating state in the EEPROM can solve the problem when there is no power, i will see in details the microcontroller solution, if the problem can be solved
Hi,
I have an LED board where i want to add a circuit to control the brightness,
input parameter of the LED board DC voltage ( 12V, 350mA),
i want to add a circuit in such a way that when the voltage turns from 12V to 0V and again 12V ( low pulse of few ms) the current decrease ( for example...
i don't understand why you need to write a long paragraph, i just asked if you are advertising, i do not see any insult in my post, sorry if you understood it as insult, it was not the intention, and i didn't accuse the rest of the forum, i don't know how you made this conclusion.
