Especially in old vehicles, electrical installation is a big problem, due to vehicle age, usage period etc. there are voltage problems. Especially in the chassis, oxidation, oiling, aging of high current cables etc. The Japanese have offered various products in terms of grounding. I decided to apply the system in my vehicle, the first part…
What is a Negative Ionizer? Air Purification and Ionization Technology A negative ionizer, also known as an air ionizer or ion generator, is a device designed to improve air quality by releasing negative or positive ions into the air. Using high voltage of approximately 5 kV, negative ions are produced, while positive voltage generates positive…
The charger ensures that the battery is charged with a constant current and then recharged after the charging current is reduced. The circuit consists of a full-wave rectifier, a current balancer and a charging current sensor. The current stabilizer works on the principle of limiting the current of the voltage stabilizer. The charging current decreases…
Welding machine project is a two-in-one SMPS Power Supply and Welding Machine built on the STM32F103 Development board. Welding Machine circuit Working frequency 45khz. Toroidal cores are used in power and driver. Voltage current information is displayed on the Oled LCD screen and adjustment is made with the encoder. Thanks to @devrecii for preparing the…
The lead battery activator prevents the formation of crystalline sulphate deposits on lead plates. Crystalline sulphate deposits form especially in lead batteries that have been stored for a long time, used rarely or discharged with low current. The life of the battery can be significantly extended by the desulphator device. A different design compared to…
Regulator, Power Supply I have completed the power supply, which is the second phase of the Big Breadboard project, and boxed it up. It could have been all together under the breadboard plate, but this is fine as it is, it was a very long project anyway, no need to bother anymore, it works. Power…
I gave the device in the Breadboard Box project that I shared before to my friend as a gift. He loves electronics (especially analog electronics) and since he makes lots of circuits, the Breadboard power supply system was very useful for him. I continued as before for a while. Finally, I finished my new big…
Active PFC supported SMPS power supply is made with IR2156 Ballast driver integrated circuit. Active PFC section uses MC33262 active power factor integrated circuit. Output voltage of SMPS circuit on load is 2X40VDC PFC output voltage is 400V There is source PCB drawing of Active PFC Power supply project (sprint layout 6) also MC33262 PFC…
Switched power supply, SMPS circuits can take a long time to repair, continuous measurements are made, electricity is supplied, re-checking, etc. When the input voltage 220VAC is cut off, there will be a voltage between 300VDC….320VDC on the DC high voltage line (in active PFC circuits, it can be 380V or higher) because the filter…
While I was thinking that there is no worse, dangerous, low-quality design for 18650 Rechargeable Li-Ion batteries and chargers, I encounter much worse chargers and batteries. The batteries of the LED Headlamp are completely dead, the charger is extremely low-quality and weak, so I placed a TP4056 module in the charger so as not to…
