Figure 1: Set-up of the DC/DC converter for determining losses
As switching frequencies climb into the megahertz range and power densities continue to rise, power inductor losses have become a decisive factor in overall converter efficiency. Würth Elektronik's low-loss inductor technologies—from advanced core materials to flat wire windings—help engineers push high-effic

In today’s data acquisition systems (DAQs), performance boundaries are continually being pushed. System designers require higher speed, lower noise, and better total harmonic distortion (THD) performance; all of which are possible but none of which are free. These performance improvements typically co

The EPCOS PQSine active harmonic filter
To a non-engineer, the word “harmonics” has a beautiful sound – one that to many conjures up an image of a concert with instruments playing beautiful music. The harmony is what combines with the melody to turn the composition into something complex and beautiful rather than being just a simple tune.
However, when most

The creepage distance is the shortest path between two conductors along the surface of an isolator (typically a PCB)
When designing a switch-mode power supply (SMPS) operating losses and the ability to dissipate heat are critical selection criteria for MOSFETs. The standard TO-220 package is generally good at dissipating heat and the wide range of heatsinks and forced-air cooling options available can easily improve this. Le
