Over Current Cut-off Power Supply Using Arduino
In this post I will show how to construct a battery eliminator / DC variable power supply which will automatically cut-off the supply, if the current flow through the load exceeds the preset threshold level. Main Technical Features The proposed over current cut-off power supply circuit using Arduino has 16 X 2 LCD display, which is […]
How to Design a Bench Power Supply Circuit
In this post I have explained how an effective and efficient, yet very cheap, and stabilized bench power supply can be designed by any electronic hobbyist for safely testing all types electronic projects and prototypes. The main features that a bench power supply must have are: Audio/Video Representation General Description The majority of the power […]
4 Simple Transformerless Power Supply Circuits Explained
In this post I have explained 4 easy to build, compact simple transformerless power supply circuits. All the circuits presented here are built using capacitive reactance theory for stepping down the input AC mains voltage. All the designs presented here work independently without any transformer, or no transformer. The Transformerless Power Supply Concept As the […]
Adjustable Switching Power Supply Circuit – 50 V, 2.5 Amps
The explained variable switching power supply circuit is designed around the integrated switch mode power supply controller device Type L4960 from SGS. The main features of this switching regulator can be summarized from the following data: Main Features Input voltage range: 9-50 VDC Output voltage variable from 5 to 40 V. Maximum accessible output current […]
LM317 Variable Switch Mode Power Supply (SMPS)
So far in this website we have studied LM317 based linear power supply circuits, here I have explained how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage […]
