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..

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..

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..

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..

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..

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 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..

BEKA-MAX Type S-EP 4 pump is used for central lubrication of various mechanisms and equipment units. BEKA-MAX Since there is no IMS 559. 392 integrated in the original pump card,..

@Kapibara shared the battery desulfator circuit for battery resuscitation, recovery of the dead battery, I made a similar desulfator circuit for battery repair and tested for a long time. NE555..

ESR meter is a device used to measure the equivalent series resistance (ESR) of capacitors. Built on the PIC16F690 microcontroller, the previous version uses PIC16F873A) The ESR meter circuit is..
