How to Calculate Transformerless Power Supply Circuits
In this article I have explained how to calculate resistor and capacitor values in transformerless power supply circuits using simple formulas like ohms law. Analyzing a Capactive Power Supply Before I have explained the formula for calculating and optimizing resistor and capacitor values in a transformerless power supply, it would be important to first summarize […]
Automatic Voltage Stabilizer Circuit for TV sets and Refrigerator
Here we will study the design of a simple automatic mains AC voltage stabilizer which can be applied for safeguarding appliances like TV and refrigerators from fluctuating voltages. A voltage stabilizer is a device which is designed to sense inappropriate voltage fluctuations in AC mains supply inputs, and correct them to produce a stabilized voltage for the […]
How to Connect Two or More Transistors in Parallel
Connecting transistors in parallel is a process in which the identical pinouts of two or more transistors are connected together in a circuit in order to multiply the power handling capacity of the combined parallel transistor set. In this post I have explained how to safely connect multiple transistors in parallel, these can be BJTs […]
