Spread spectrum frequency modulation, soft-switching, snubbers, and proper grounding and shielding all help minimize emissions at source. Shielding Proper enclosure shielding and correct filter feedthrough component installation is critical to contain radiated emissions. PCB stitching vias help shield leakage...
Such disturbances may also couple with other near wires, leading to bad performance and possibly also failures. Figure 13. Worst case for conducted emissions: switching an inductive load without a snubber for recirculation GADG2509171305PS AN5084 - Rev 1 page 10/33 AN5084 Example of...
Figure 13: An RC snubber of the SSR output prevents false turn-on due to inductive loads. (Image source: Omron Corp.) The situation for DC SSRs is similar but somewhat simpler. If the load is inductive, the current spike it generates when it is switched off can damage the now open ...
you can choose to connect a freewheeling diode and inductor in parallel to the inductive load to form a freewheeling loop when it is turned off, releasing the induced energy to protect the MOSFET, if necessary , Can also add RC snubber circuit (Snubber) to suppress voltage spikes. (Note ...
