High Voltage Transistors BUX 86 and BUX 87 – Specifications
In this article we are going to make an effort to understand the technical specs of the BJTs BUX86 and BUX87 which are high voltage complementary paired transistors. Introduction The Bux 86 and BUX 87 are typically high voltage switching transistors with silicon epibase. They come in TO-126 package and are NPN types. These devices […]
Difference Between Current and Voltage – What is Voltage, What is Current
The following data explains the important aspects connected with the electrical parameters like voltage and current, the content also explains in simple words how to differentiate the two parameters. What is Current It is the number of electrons flowing at any instant through a conductor or across the positive and the negative of a conductor […]

2-Stage Mains AC Voltage Stabilizer Circuit
In this article I have explained how to make a 2 relay or two stage mains AC voltage stabilizer circuit for controlling and regulating 220V or 120V mains voltages through a simple circuit. Introduction In this power stabilizer circuit, one relay is wired to select the high or the low tap from the stabilizer transformer […]
SCR/Triac Controlled Automatic Voltage Stabilizer Circuit
In this article I have explained a relatively simple triac controlled automatic mains voltage stabilizer circuit, which uses logic ICs and a few triacs for controlling the mains voltage levels. Why Solid State Being solid state in design, the voltage switching transitions are very smooth with minimum wear and tear, resulting in efficient voltage stabilization. […]
