    atx power supply for robot

    Kumar, Yes you can raise the voltage to more than 24 volts but there is a very low current output from the ICL7660/62. The PC PSU is a SMPS. 7A is not a problem. Yes negative supply is also available.

    pwm in stepper

    Kumar, You must use a motor rated for the load in your application then you can stop it just by stopping the pulses. PWM is used for other kinds of motors. If you exceed the holding torque by applying more current you will damage the motor in a very short time. It is possible to use some kind...

    Schematics Variable current 12v 60A to 0A

    Mud is the word my friend, ;D on some points I can see what you are aiming for. If you want an indication that the engine has started just use the charge indicator light. This takes no sophisticated electronics to achieve. When the ignition is turned on (see picture) the charge indicator lamp...

    LM317 Variable power supply

    Emiliano, 1.Yes bigger filter capacitors will improve the ripple rejection but so will a series inductor (choke). 2.The inrush current will increase with bigger caps so a bigger bridge is necessary. 3 It is possible to use one half of the transformer for a
