A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the ...

And this voltage regulator circuit is quit easy to build on our self by using LM317 voltage regulator IC. In this post I’ll show you step by step procedure how I build my own LM317 based variable ...

Voltage regulators are essential components in many electronic circuits, as they provide a stable and constant output voltage from a variable input voltage. They are used to power sensitive ...

A very simple variable power supply circuit can be made using this electronic circuit diagram .This variable regulator circuit will provide an variable regulated output voltage , between 0 and 50 ...

Fig. 2 shows the circuit for increasing the output voltage of a regulator circuit using a pair of voltage-divider resistors. Let’s assume the value of R1 as 470 ohms, which means that a constant ...

3 Power converter design The third step in designing a hardware circuit that can handle variable and intermittent power sources is to design the right power converter for your application.

Surprising facts, like “old fangled” 3-leg linear regulators (LM317, LM337, LM350, et al.) can be used in shunt regulator topologies can sometimes inspire “new fangled” circuit designs. Figure 1 shows ...

Circuit of the 12V battery charger-cum-variable power supply is shown in Fig. 1. It is built around two LM138 variable voltage regulators (IC1 and IC2), dual op-amp LM358 (IC3), 12V voltage regulator ...

Project Statement Design and simulate a variable power supply which takes an AC input of 230V rms at 50 Hz and gives a DC output that can vary in the range of 0-30V and maximum output load current ...

Given a noisy input and a variable load, a voltage regulator will give a nice clean, stable output voltage. We’ve covered the basic operation and usage of the LM317 many times.

Abstract: In this paper construction of a system with the stabilization of the current value of the variable voltage and frequency based on variable voltage regulator with voltage boost with PWM ...
