In this post I have explained a voltage high current doubler circuit which will almost double the voltage that’s been applied at the input (up to 15V max), and also it becomes specifically useful since it allows higher current loads to be used at the output, in the order 10 amps. Since the voltage doubler […]

High Current Transformerless Power Supply Circuit
The simple configuration of a transformerless power supply circuit presented below is able to provide high current at any assigned fixed voltage level. The idea seems to have solved the problem of deriving high current from capacitive power supplies which earlier seemed a difficult proposition. Introduction I have discussed a few transformerless power supply circuits […]
How to Drive High Watt LEDs with Arduino
In this post I have explained the method of incorporating high watt LEDs with Arduino through external high voltage supplies. The question was put forth by Mr. Cole. The Circuit Question I stumbled upon your blog and I love it! So much great information and great ideas Right now I am trying to figure out […]
High Current Adjustable Switching Power Supply Circuit using L296 IC
The L296 is a monolithic power switching regulator IC, incorporating an adjustable output voltage, current limiting, and thermal shutdown. Due to these features, this IC has become a favorite option for a many different applications such as bench power supplies, battery chargers, and motor controllers. The IC L296 will be used in this circuit to […]
Flashlight Circuit with Long Backup and High Efficiency
There are two main advantages of this highly efficient flashlight circuit with long backup. Firstly, it uses only a single 1.5V AAA cell and illuminates a 3.3V LED. Secondly, the 1.5V cell is consumed by the LED until there’s virtually no charge left in it. Due to these features, this flashlight is able to last […]
Regulated, High Current Power Supply Circuit
The circuit I have explained below can be used for applications that require stringent voltage regulations and ripple rejection criteria. The transistor pair are configured such that all residual ripple factor are perfectly rectified. Circuit Operation The circuit below shows a simple way of acquiring a perfectly regulated and stabilized high current DC voltage output using ordinary transistors. The circuit […]
