App note: Safety considerations for Silicon Labs series capacitor isolators

Great in-depth about electronic isolators from Silicon Labs. Link here (PDF) Isolators are widely used in automotive, telecom, industrial, and medical applications to provide protection for people and/or equipment from high voltage hazards. The robustness of the isolator’s insulation, or “isolation barrier”, over the operating life of the equipment is key to ensuring safety against […]

High resolution capacitance meter project

Puretus has been working on  a high resolution capacitance meter: One day I was looking for methods to measure capacitances of cap components. Even though it is pretty trivial now with my new Brymen  multimeter, I ran into this design by Roman Black which turned out to be very well explained and in terms of […]
