Abstract |
|
The aim of development of this project is towards providing efficient and simple method for control speed of DC motor using PWM technique. The modulation of pulse width is obtained using scimit trigger and rectifier. There are several method for controlling the speed of DC motors. One simple method is to add series resistance using rheostat. As considerable power is consumed in the rheostat, this method is not economical. Another method is to use a series switch that can be closed or opened rapidly. This type of control is termed as chopper control. The PWM based circuit smoothy control the speed of general purpose DC motor. To get desired modulation of pulse width as output, we have used schimit trigger and rectifier within regulator as the source of varying output. |
