I did not like the PCB design of this application of Elektor and rearranged it myself. 🙂 There is even another variation of the same scheme on the site. (12 Volt 24 Volt DC DC Converter Circuit BUZ11) The aim is to make the circuit board smaller and get rid of the heat sink issue.…
The 10W LED Driver driver circuit is designed to operate a 10 watt LED matrix (3×3, 10-12V) with current limitation. It works in the Step-Down system. The ring core used for the 500uh coil is approximately 80 turns of winding with 0.55 mm diameter wire taken from the filter located on the output stage of…
Transistor 2X100W stereo and mono bass amp circuits by converting 12V battery voltage (between 11v…14.4v) SG3525 DC DC voltage amplifier circuit to around 2X30…35V. There is protection against short-circuiting in both circuits and short-circuiting of the transistors at the amplifier output and giving DC voltage. The 120W subwoofer amplifier has an adjustable bass filter circuit…
My brother Hasan is an old project of two channels 300w and 500w versions. Pre-shared 500W 250W Hi-Fi Transistor Amplifier Circuits and SG3525 EI33 ATX 200-600w DC-DC Converter for auto amplifier projects Output power transistors of the Amplifier Circuits 2SC5200, 2SA1943 DC DC converter floor SG3525 pwm control integration is used. EI33 transformers are used…
Even though regulated circuits over transformerless direct mains voltage are not recommended, they are used in many circuits, products, especially in the lighting industry. In general, simple regulated circuits with serial capacitors and zener are used. This circuit is made of more advanced 2-stage regulated. In this way, high output current is provided. 230v mains…
Switch Mode DC DC Adjustable Power Supply The TL494 system is the heart of the stabilizer. Elements C13-1.5NF, R14-10K set the frequency of the internal generator work to about 77 kHz. Comparator first, along with elements R7, R8, R9, R15, R16 and C14 are the output voltage stabilization circuit, which the value is regulated by…
Previously shared RMS 250W auto amplifier JBL filter SMPS EI35 SG3525 project is similar to the PCB design is a very regular auto amplifier circuit. You can use 2x100w rms stereo or 200w rms mono, which can be controlled by bridge connection as well as bass control with cross over circuit with adjustable TL072P op…
The input voltage of the 600W DC DC Buck Converter circuit is 35V … 60V DC. output 12V 50A LM5116 for control of the DC DC Buck Converter is capable of use Adjustable operating frequency from 50kHz to 1 MHz available Current limit, soft start etc. it has a lot of features. The output power…
SMPS Soldering Station Circuit However, this voltage is linear increasing tendency due to the existence of the magnetizing current of the main transformer and due to the limited inductance of the inverter output choke. By comparing this actual current flow (pin 3 UC3845) with the setpoint setpoint (pin 1 UC 3845) is directly generated PWM…
UC3843D STEP-UP for supplying of notebook in car. Introduction presents dividing of switching power supplies followed by a choice and a proposal of power supply. In this work we can find the specific proposal of inductor, the proposal of electronic connexion and the proposal of PCB layout. In the last part of work there are…
