Designing Simple Power Supply Circuits
In this post I have explained how to design and build a simple power supply circuit right from the basic design to the reasonably sophisticated power supply having extended features. Power Supply is Indispensable Whether it’s an electronic noob or an expert engineer, all require this indispensable piece of equipment called the power supply unit. This is because no electronics […]
IC 7805, 7812, 7824 Pinout Connection Explained
In this post I have explained how to connect common 78XX voltage regulator ICs such as 7805, 7812, 7824 etc for getting fixed regulated output voltages at 5 V, 12 V, or 24 V outputs respectively. The input voltage must be at least 3 V higher than the desired output voltage. For example, if a […]
Simple 12V, 1A SMPS Circuit
In the following content I have explained two simple 12V, 1 Amp switch mode power supply (SMPS) circuit using the very reliable VIPerXX IC from ST microelectronics. With the advent of modern ICs and circuits, the age old iron transformer type of power supply are surely becoming obsolete. Today power supplies are much compact, smaller […]
How Switch Mode Power Supply (SMPS) Circuits Work
SMPS is the acronym of the word Switch Mode Power Supply. The name clearly suggests that the concept has something or entirely to do with pulses or switching of the employed devices. I have explained how SMPS adapters work for converting mains voltage to a lower DC voltage. Advantage of SMPS Topology In SMPS adapters […]
How to Make a Bridge Rectifier
A bridge rectifier is an electronic network using 4 diodes which is used for converting an AC input to DC output. The process is called full wave rectification. Here I have explained the basic working principle of rectifier diodes such as a 1N4007 or a 1N5408, and also learn how to connect 1N4007 diodes to […]
