EMI is a common problem engineers face when designing a new application. How can a developer solve EMC problems on the circuit board or prevent them from occurring? What has to be considered and where does it make sense to use a filter? Which system impedances are there and what are the deciding factors for which filter topology should be used? In …
 
Choosing the appropriate components is vital for the efficiency of DC/DC switching regulators with relatively high input and output currents. A high-efficiency switching regulator is market-ready if it, and the end product, comply with all necessary EMC standards; meaning more filters must be included at the input and output to reduce interference.…
 
Recently, the need for disinfection technologies has skyrocketed. One of these technologies is disinfection using UV-C LEDs.
