    What're design rules to consider in order to have the best chance of complying with EMC requirement?

    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...

    Three-phase EMI filter. LTspice

    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...

    Help with EMI Ferrite (magnet?) Rings

    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...

    How do I simulate these two different Line Impedance Stabilization Network (LISN) models in LTspice?

    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...

    Electromagnetic interferences - how to handle?

    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...
