Circuit Schematic Mobile Phone Battery Emulator using LM317 IC

Battery. - This is one a circuit schematic of Mobile Phone Battery Emulator using LM317 IC look like in Figure 1 below. In this circuit schematic the basic component used is LM317 IC as the regulator component. 

In here we will give you global description about this circuit schematic of Mobile Phone Battery Emulator using LM317 IC and then we will give you link to continue your reading from original site from the external website.

Circuit Schematic

Component Part

  • LM317
  • LED
  • Resistors
  • Capacitors
  • Variable resistor
  • Connector
Description

Circuit schematic like in Figure 1 above is Circuit Schematic Mobile Phone Battery Emulator using LM317 IC. Electroschematics site describe that the typical target voltage of the Li-ion battery is 4.2 V (note that the target voltage is not the same as the nominal voltage, as it is 3.7 V typical). An adjustable voltage regulator is designed as the mobile phone battery emulator. The circuit based on the popular three-pin adjustable voltage regulator LM317T (IC1) receives external dc input of 9 V/2 A through input connector J1. The output voltage available at connector J2 can be adjusted from just below 3 V to just above 4 V with the help of the 500-Ω multi-turn preset pot (RP1). Although most devices powered by Nokia batteries appear to work well at about 4.2 V, a little bit of experimentation with the values of resistors R2-R3-RP1 may be necessary. As stated earlier, the 82-kΩ resistor (R4) is essential to fooling the device into thinking that a real battery is attached at its battery connector.

PID and Predictive Control of Electrical Drives and Power Converters using MATLAB / Simulink 1st Edition Free Download by Liuping Wang

Robometricschool. - This is one of the MATLAB programming book for you who want to learn more about PID and predictive control using MATLAB. This book titled with PID and Predictive Control of Electrical Drives and Power Converters using MATLAB / Simulink 1st Edition by Liuping Wang.


In this time we will give you global description about this book and then we will give you the link to take free download e-book of PID and Predictive Control of Electrical Drives and Power Converters using MATLAB / Simulink 1st Edition by Liuping Wang from external server.

Description

PID and Predictive Control of Electric Drives and Power Supplies using MATLAB/Simulink examines the classical control system strategies, such as PID control, feed-forward control and cascade control, which are widely used in current practice.  The authors share their experiences in actual design and implementation of the control systems on laboratory test-beds, taking the reader from the fundamentals through to more sophisticated design and analysis.    The book contains sections on closed-loop performance analysis in both frequency domain and time domain, presented to help the designer in selection of controller parameters and validation of the control system.  Continuous-time model predictive control systems are designed for the drives and power supplies, and operational constraints are imposed in the design.    Discrete-time model predictive control systems are designed based on the discretization of the physical models, which will appeal to readers who are more familiar with sampled-data control system. Soft sensors and observers will be discussed for low cost implementation. Resonant control of the electric drives and power supply will be discussed to deal with the problems of bias in sensors and unbalanced three phase AC currents.

Description

According Circuitstoday site describe that this circuit is a simple and efficient PWM lamp dimmer using timer IC NE555 is discussed in this article. Yesterdays linear regulator based dimmers can only attain a maximum efficiency  of 50% and are far inferior when compared to the PWM based dimmers which can hit well over 90% efficiency. Since less amount of power is wasted as heat, the switching elements of PWM dimmers require a smaller heat sink and this saves a lot of size and weight. In simple words, the most outstanding features of the PWM based lamp dimmers are high efficiency and low physical size.

Circuit Schematic a Simple Function Generator with an LM324 Op Amp Chip

Robometricschool. - This is one circuit of simple Function Generator with an LM324 Op Amp Chip like in Figure 1 below. The main component are used in this circuit is Op Amp LM324 Chip.

In here, beside we will give you circuit of Function Generator with an LM324 Op Amp Chip, we also will give you component part and description. And the last we will give you link to take read more about this circuit from original source.

Circuit


Component Part
  • Capacitors
  • Resistors
  • Variable Resistor
  • LM324 IC
Description

According Learningaboutelectronics site describe that this circuit is pretty basic. The first op amp produces a square wave. We feed this square wave into an integrator circuit, which outputs a triangle wave. We then feed this triangle wave into a second integrator circuit, which outputs a sine wave.

The 100KΩ potentiometer allows for a pretty good wide range of frequencies so that the circuit offers good frequency adjustment, as a standard function generator would.

The circuit also can easily allow for amplitude adjustment. If you're using a DC power supply to power this circuit, then all you have to do is adjust the voltage on the DC power supply to change the amplitude of the signal. If you're powering the circuit through batteries, then you'll need add the number of batteries you would need to get the maximum voltage you want and then you add a small-valued potentiometer, such as 200Ω-500Ω, to allow for voltage adjustment.
