This is a Simple Battery Charger with Automatic Switch-off Circuit Diagram . This lovely charger automatically switches off when your rechargeable batteries reach the full charge.The circuit comprises a bistable multivibrator wired around timer IC 555. The bistable output is fed to an ammeter (via diode D1) and pot meter VR1 before it goes to three Ni-Cd batteries that are to be charged. Battery Charger with Automatic Switch-off Circuit Diagram Normally, the full charge potential of an Ni-Cd cell is 1.2V. Trigger the bistable by pressing switch S1 and adjust potmeter VR1 for 60mA current through the ammeter. Now remove the ammeter and connect a jumper wire between its points ‘a’ and ‘b.’ Connect the positive output terminal of the batteries to the emitter of pnp transistor T1. The base of transistor T1 is held at 2.9V by adjusting potmeter VR2. The output of transistor T1 is inverted twice by npn transistors T2 and T3. Thus when the batteries are fully charged to 3×1.2V=3.6V, a voltag...

Power amplifier Class-B is the most popular operating modes, and possibly more than 99% of the current series of power amplifier designed and manufactered are of this class. Defining the Class-B is the amount of bias voltage that causes conduction of both output devices to overlap with the current and thus produce the minimum amount possible crossover distrosi. This Class-B power amplifier performance : Power Output________________________50W RL Impedance_______________________8R Distortion__________________________Below 0.0006% at 1 kHz and 50W/8R Slew rate___________________________Approximately 35V/us Noise______________________________-91dBu at the output EIN_______________________________-117dBu (referred to input) Frequency response__________________+0, -0.5dB over 20Hz-20kHz Part List : Resistor R1,R8____________________________10K R2,R3,R13________________________100R R4_______________________________150R R5,R10___________________________1K R6,R7____________________________68R ...

 Description: To make the Servo system to work stably and most effectively, it is necessary to adjust the circuit loop gain value of the servo drive properly. This option provides some effective tools to optimize the operation of the servo system   Path: The user can click Tools -> Auto Gain Tuning command from the menu bar or click on the icon directly  on the tool bar to execute this option and open the following dialog box.   Functions:  There are two tabs in this dialog box, one is Off-line Computation (Static Auto-tuning) and the other is  On-line Auto Tuning (Dynamic Auto-tuning) . Please refer to the following descriptions for the functions: 1) Off-line Computation  (Static Auto-tuning)  When not connecting to the servo drive, pressing “Compute” button can calculate the value of the related gain parameters and display in the Calculation Result Area on the screen according to the conditions (B.W., JL/Jm, and Rigid Holding) se...
