Figure 1: Contact wear in an electromechanical relay
As a mature technology, electromechanical relays and circuit breakers are well established, however they continue to suffer from some inherent weaknesses. Moving to solid-state technology can address these but introduces its own challenges. So, what is the right solution?

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,

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

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.
