Regulated Power Supply 0.24V 0.8.5A ATX Modified
I made an application about converting the old generation ATX power supply to a 0.24v 0.8.5A regulated power supply, as in the project of converting the computer power supply to a battery charger that I shared before. The price of regulated power supplies has increased, this power supply is very useful in your workshop, and…
Making a High Current Shunt Resistor
Since I don’t work at very high powers, power electronics, measurement etc. Like many electronics, I use a stone resistor, in fact, it’s healthier to use a metal type shunt resistor, sometimes I wrap it in a shunt resistor. I don’t know how suitable the type of material used for handmade shunt resistors is, I…
Converting Computer Power Supply to Battery Charger
A modification to convert an old generation ATX or older AT computer power supply to a 4AH..100AH battery charger. You can add a TL494 controlled module to the power supply and make a high power charger that works very well after a few tweaks. The output voltage of the circuit can be adjusted between 10.6v….17v…
Breadboard Power Supply Box
It is very practical to make circuits with a breadboard, especially in circuits with less material. Sometimes I build mixed circuits, but usually simple circuits. In the breadboard experiments, the power supply started to be a problem. It takes some time, especially when 2 or 3 different voltages are required, especially if symmetrical voltage is…
12V 20A Lead-Acid Battery Charger TL494 UC2906 ACS758
The designed SMPS charger system uses both constant current and constant voltage charging methods. It can be used to charge classic, gel and traction accumulators with a working voltage of 12 V. It can gently charge deeply discharged accumulators, but also maintain their maximum capacity during a longer shutdown. The charger is able to recognize…
2X38V 250W IR2156 Amplifier Power Supply SMPS
An SMPS switched power supply project for power amplifiers with the IR2156 half-bridge mosfet driver IC from International Rectifier (currently acquired by Infineon Technologies). Brief information about IR 2156. The IR2156 is a half-bridge half-bridge converter controller with a built-in high voltage driver and a programmable oscillator. It was designed by the manufacturer as a…
BMS 3S 25A Circuit Diagram and Modified
BMS 3S 25A is frequently used especially for Li-ion battery conversion of cordless drills. Its prominent features are balanced charging, over-current, short-circuit protection, allowing instantaneous 34-40A current flow, which is very good for high-power applications, and the PCB size is very small and the mosfets are cooled over the PCB. (although a heatsink may be…
Li-Po Lifepo4 Li-Ion Battery Protection Circuit Discharge Short Circuit
The advantages of lithium batteries are many, first of all, high power, low weight and no “memory effect”. Also, a lithium battery has three times the voltage of a nickel-cadmium or nickel-metal hydride battery (1.2V). However, lithium batteries cannot be used safely and efficiently without special control systems. The first version of the Li-Ion Battery…
12V 24V 32V Motor Driver Circuit 30A Throttle With Potential Control
The high-power control circuit motor reversing DC motor speed controller circuit features soft start, relay switching of motor direction, and PWM speed control. I have shared the circuit before. There are details in the article “High Power 30 Amp DC Motor Speed Control Circuit”, but I prepared a new article because I applied it and…
