In a triac phase control circuit, the triac is triggered ON only for specific portions of the AC half cycles, causing the load to operate only for that period of the AC waveform. This results in a controlled supply of power to the load. Triacs are popularly used as a solid-state replacement of relay for […]

LiFePO4 Battery Charging/Discharging Specifications, Advantages Explained
While Li-Ion and Lithium polymer electrolyte (LiPo) batteries possess unmatched energy density, Lithium-based batteries are costly to produce and need meticulous handling along with a cautious charging. With the advancement of nanotechnology, the manufacturing process of the cathode electrode for these batteries has seen a substantial improvement. The break through nanotechnology-based high-load LiFePO4 cells are […]
Boolean Algebra in Logic Circuits Made Easy
Boolean algebra is a assortment of basic mathematical techniques applied to signify and communicate the logical procedures that happen within a digital circuit. Difference Between Boolean Algebra and Common Algebra Boolean algebra is much like common algebra. The main distinction is that in contrast to common algebra, in which we have parameters that can be […]
How Contactless Infrared Thermometers Work – How to Make One
In this post I have explained the basic working concept of thermal scanners or contactless IR thermometers, and also learn how to make a practical DIY prototype of the unit without Arduino. In the post COVID-19 era, witnessing doctors holding a contactless temperature gun and pointing toward the forehead of a COVID-19 suspect is a […]
Simple Triac Triggering Circuits Explained
In this post I have explained the fundamental methods of triggering a triac, and also discuss the right way to connect the terminals of a triac. Triacs are solid-state bidirectional thyristors that can switch across both the AC half cycles on a 120-volt or 240-volt Ac power system. A triac could be activated (switched on and […]
Understanding MOSFET Avalanche Rating, Testing and Protection
In this post I have explained MOSFET avalanche ratings, and learn how to understand this rating in the datasheet correctly, how the parameter is tested by the manufacturer, and measures to protect MOSFETs from this phenomenon. The avalanche parameter not only helps to verify the devices ruggedness, it additionally helps filtering out weaker MOSFETs or […]
