 Electric Vehicle Power Electronics Push Test Equipment Performance Limits

Figure: LV123 Operational status vs. operating voltage ranges

Power Electronics in New Vehicle Systems Automotive electronics are changing in dramatic ways. While it is true that “traditional” internal combustion engine vehicles still dominate the market, the automotive world is racing into a disruptive future. The market demand for reduction in the use of fossil fuels

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

Music to my ears

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

Safety vs. performance

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
