    Pdf 32 Fan -Speed Control seminar report/pdf/ppt download

    Abstract:A linear circuit measures temperature and controls the speed of a cooling fan by generating a variable supply voltage for the fan.

    Fan noise is becoming a larger issue as more electronic equipment enters the office and the home. A variable speed fan permits slower, and quieter, fan speed when temperature conditions allow.

    Fan-control circuits range from simple switches that boost the fan speed at a certain temperature, to digitally controlled fans with continuously-variable speed. High-speed/low-speed switches are inexpensive, but the sound of sudden speed changes can be annoying.

    Digitally controlled fans perform well, but those circuits are more costly, and the system must include a serial bus.

    This application note presents a low cost, self-contained analog circuit for fan-speed control. Which is easily adjusted for any desired linear relationship between the fan voltage and temperature .

    Actual data points are plotted against the desired voltage .
