Find Your Digital Multimeter Soulmate

Choosing a DMM isn't as simple as it looks. To choose the right DMM for your application, there are a number of factors that you should consider.


How to Use the Arduino’s Digital I/O

How to Use the Arduino’s Digital I/O

The digital inputs and outputs (digital I/O) on the Arduino are what allow you to connect sensors, actuators, and other ICs to the Arduino . Learning how to use the inputs and outputs will allow you to use the Arduino to do some really useful things, such as reading switch inputs, lighting indicators, and controlling relay outputs.

Switching Losses: Effects on Semiconductors

Switching Losses: Effects on Semiconductors

We review switching losses involving diode recovery charge, transistor switching with clamped inductive load, device capacitance and leakage, package, and stray inductances, and the efficiency versus switching frequency curve.


Modeling the Pulse-Width Modulator

Modeling the Pulse-Width Modulator

Pulse-width modulation can be of many forms. A PWM signal of constant frequency can be obtained by comparing the ramp signal (or carrier signal) with the error between the desired and the actual output voltage signal (Vc, compensator voltage signal).
