High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

Don’t get zapped when buying a new high-voltage DC power supply. Understand the specifications first. Lasers, linear accelera-tors, X-ray machines, defibrillators, radar, and numerous other ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

Measuring rise time for a power source. Voltage vs. time signals measurements via a scope. A practical setup for battery testing. I was recently asked a question about a dc power supply, aka a voltage ...
