POWER ELECTRONIC PROJECTS Archive

The charging circuit current is adjustable between 0 and 5A. The output voltage is pulsed for fast charging. Additionally, an integrated voltage monitor automatically reduces the charging current when the..

In my article “How to Spot Weld Batteries? Tips & Tricks,” I provided detailed information about spot welding batteries. I’m not an expert; I’m researching and applying the techniques, and..

An Arduino Nano-based spot welding machine for spot welding 18650 batteries. All the details of the Arduino spot welding machine project, including 3D drawings, are shared. The spot welding machine..

Transformer Tester: After designing a microcontroller-based wide-range ring tester, the question arose whether a basic version of the Coil Tester could be designed, usable by anyone with electronics skills, using..

In power electronics, an active DC rectifier module using MOSFETs increases efficiency and minimizes losses. MOSFET rectifiers can advantageously replace both classic silicon diode and bridge rectifiers, as well as..

A simple current direction indicator device for monitoring current balance in older vehicles, battery chargers, UPS backup power supplies, or differential devices. A two-color LED is used for the current..

Some battery-powered electronic devices are designed for occasional use. Users often forget to turn them off, which causes the battery to drain quickly. In particular, some multimeters lack an automatic..

I don’t usually share power supplies that aren’t used in practice, but this project design is interesting, with a good power and voltage range. It’s a regulated power supply that..

Analog industrial transmission standards are still in use, as evidenced by the wide range of sensors available on the market. Existing systems sometimes require maintenance or expansion with new sensors…

Regulated power supply can be adjusted between 0.20 Volt 8 Ampere or 0.40 Volt 4 Ampere according to the selection. Current limiting between 0V and 20V 2mA..8A. High output voltage,..
