emi

Hello guys, I am designing a 2 layer PCB that contains a power part (PSU, Relays) and digital one (MCU, digital & analog I/Os, ..)... I looked up some design rules that should minimize EMI but i am not sure if those rules I applied are sufficient for my board to be EMC compliant!! here are the...

Hello. Could you help me understand how to create a three-phase EMI filter? For example, I chose a full-bridge inverter with parameters P = 100kW, f_switch = 100 kHz. The noise measurement is performed using the LISN. The results of the simulation (calculation time 0-50ms) In this graph...

Could someone point me to where I can research, measure, calculate, and/or size these ferrite rings if voltage and rough max amps are known? It's for 5, 12 and 24VDC low power system pulling up to 2 to 3 AMPs per run. Some amps are far lower. Also would like advice about bundling several...

So, I found these models for Line Impedance Stabilization Network (LISN) in two different books. I want to simulate these two models in LTspice, but I don't know which side to connect the EUT and which side to connect the spectrum analyzer and ofcourse, where to connect the source? and how do I...

Hi everyone, I'm working on a little DIY lamp project with a capacitive switch. The kit consists of a breadboard with some components, a battery and its charging PCB, and a 20cm-long electric wire that leads to the aluminium foil used as capacitive sensor. The lamp switch on and off randomly...
