Arduino Mains Failure Battery Backup Circuit
In this article I have explained a simple mains failure backup circuit for providing Arduino boards an uninterruptible supply during such situations. The idea was requested by Mr. Fredrik. Technical Specifications This blog gave me a lot of interesting information. Especially the power supply circuit with battery backup part. The reason for this is that […]
0 to 50V, 0 to 10amp Variable Dual Power Supply Circuit
In this post I have explained a simple yet very useful 0 to 50V dual power supply circuit which will enable a full 0 to maximum dual voltage +/- control of the input power supply DC. It also includes a wide range current control feature right from 0 to 10 amps. The idea was requested […]
Greenhouse Motorized Water Diverter and Humidity Controller Circuit
In one of the previous posts I have explained the making of a greenhouse temperature controller circuit, here we study how the effects may be enhanced through an automatic water valve actuator and humidity controller circuits. The idea was originally requested by Mr. Leandros Komninos Technical Specifications Found one on ebay, these are the detail […]
5kva Ferrite Core Inverter Circuit – Full Working Diagram with Calculation Details
In this post I have explained the construction of a 5000 watt inverter circuit which incorporates a ferrite core transformer and therefore is hugely compact than the conventional iron core counterparts. Block Diagram Please note you can convert this ferrite core inverter to any desired wattage, right from 100 watt to 5 kva or as […]
SMPS Welding Inverter Circuit
If you are looking for an option to replace conventional welding transformer, the welding inverter is the best choice. Welding inverter is handy and runs on DC current. The current control is maintained through potentiometer. By: Dhrubajyoti Biswas Using Two Switch Topology When developing a welding inverter, I applied forward inverter with two switches topology. […]
