In this post I have explained what are gel cell batteries and also learn how to build a specialized charger for charging a gel cell battery, with full calculations. The proposed circuit works in two modes: it starts charging a discharged gel cell battery with constant current, until the full charge voltage is reached across […]

High Voltage Constant Current Source Circuit
The presented circuit offers an adjustable constant current source capable of reaching up to 60mA, operating at voltages as high as 350V. Circuit Description The input stage, consisting of resistor R1 and zener diode ZD1, delivers 8V to the regulator (a 7805), maintaining this voltage relative to its reference line. This voltage level ensures sufficient […]
Constant Torque Motor Speed Controller Circuit
In this post I have explained a DC Motor controller which features a constant torque compensation for enabling the motor to run at a consistent speed irrespective of the load on it. Drawback of Ordinary Speed Controllers One drawback of the majority of simple speed controllers is they only provide the motor with a predetermined […]
