How the Switching Frequency Affects the Performance of a Buck Converter
https://www.electronics-lab.com/switching-frequency-affects-performance-buck-converter/
The buck converter uses an inherent switching action to regulate voltage. This switching frequency can affect the performance of a buck converter,and is thus very important. This application report analyzes the influence of switching frequency on buck converter performance in terms of efficiency, thermals, ripple, and transient response. It also shows bench test results at […]

Three “Project-X-A1” Pico-ITX boards have been launched by ActPower Taiwan which supports Raspberry Pi HATs and homegrown expansion modules. The prices are between the range of $44 to $76 and run Linux on Allwinner H2+, H3. and H5 SoCs. The Project-A1-series comes with three different SoC choices from AllWinner, the H2+, the H3 and the […]
How to lower relay power consumption
https://www.electronics-lab.com/lower-relay-power-consumption/
Clever way of starting-up relays discussed in this app note from Maxim Integrated. via dangerousprototypes.com Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a relay coil may be unattractive for battery-operated applications. You can lower […]
Arduino OLED Hygrometer and Thermometer using DHT11
https://www.electronics-lab.com/arduino-oled-hygrometer-thermometer-using-dht11/
Hygrometers are used to determine the moisture content of the environment. They find application in farms, food storage, museums, and other places where moisture needs to be monitored to ensure damage is not done to goods and other things stored in that space. For today’s tutorial, we are going to build a Hygrometer using the […]
Chemical sensor monitors sewage waste waters to expose polluters
https://www.electronics-lab.com/chemical-sensor-monitors-sewage-waste-waters-expose-polluters/
A new sensor system developed by Fraunhofer researchers and their partners could help safety agencies identify wrongdoers who covertly discharge hazardous wastewater into sewers to avoid specific disposal costs. By and large, safety agencies currently have no means of detecting this kind of environmental crime on a broad scale. But this illegal sewage poses major […]

Amplifier Classes
https://www.electronics-lab.com/article/amplifier-classes/
Introduction Amplifiers are commonly classified depending on the structure of the output stage. Indeed, the power amplification really happens during that stage and therefore the quality and efficiency of the output signal is dictated by the architecture of the amplifier’s output. The classification consists of an alphabetical arrangement A, B, AB and C that relates […]
