Audio Spectrum Analyzer Circuit 100 LED 10 Ch Peak Hold

I made a visually different version of the 10 channel 100 Led Spectrum Analyzer circuit that I used in the 2.1 sound system. The filter quality of the Led Spectrum..

Mosfet TL431 10W LED Driver Circuit

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..

Fan Ventilator Speed Control Wind Breeze

The author said to work in the form of “Sea Breeze” for the fan, but I thought of saving electricity. The speed control circuit of the fan works intermittently in..

SG3525 220W 300W 1000W SMPS Circuits 2X70V 2X35V 14V

2X84V 2X35V 14V 220W 300W 1000W SMPS circuits based on the SG3525 PWM control IC have been designed with a 14v output of the 300W output, and the SG3525 current..

SG3525 DC DC 2X100W 1X120W Car Amp Circuits

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..

LED Lighting Driver Circuits 300V 35V

Power LED driver Circuits made with TL494 pwm IC and MC34063 DC DC voltage converter ICs for LED Lighting. Actually there are a few more but I don’t mention them..

Electric Bicycle BLDC Motor Control Circuits 500W 1000W

A few months ago, a friend said that the electric bicycle brain was faulty, so I said bring it and we’ll see. High power BLDC motor control documents can be..

230V 3 Phase Inverter with PFC FNA41560 PIC33FJ32MC102

The inverter is fed from a single phase with 230V alternating voltage with a power of about 400W. The output gives a 3-phase voltage of 3x230V. Inverter diagram, dsPIC33FJ32MC102 software,..

12V 1AH-10AH Battery Charger Circuit (Automatic Float Charge)

12V Battery Charger for Current Limiting Lead Acid SLA (WET, MF, AGM and JEL). The battery charging circuit SLA uses a two-step process to charge the batteries. It automatically switches..
