Single Phase Semi Converter Fed DC motor drive

Experiment:Single Phase Semi Converter Fed DC motor drive Aim:   To study the operation of Single Phase Controlled DC Drive using Armature Control method. Learning Objectives: To study speed variations of a DC shunt motor. To study open loop and closed loop controls. To study armature and field control for speed control of DC motor Apparatus : Experimental kit DSO/CRO (Unearthed) Multimeter Patch cords and DSO probes Prerequisite Test Theory: DC motors: DC Motors plays an important role in energy conversion process. It is a machine which converts electrical energy into mechanical energy. In mechanical system, speed varies with number of task so speed control is necessary to do mechanical work in a proper way. It makes motor to operate easily. DC motors have been used in industrial applications for years. Coupled with a DC drive, DC motors provide very precise control. DC motors can be used with conveyors, elevators, e...

  Experiment : Micro controller Based DC Drive   Aim:   To study the operation of Microcontroller based DC drive System Learning Objectives: To study speed variations of a DC motor To study open loop and closed loop controls. To study Micro computer based dc drive Apparatus : Experimental kit DSO/CRO (Unearthed) Multimeter Patch cords and DSO probes   Pre Test Theory Microcomputer control of DC drive   The analog control scheme for a converter fed dc motor drive can be implementedbby hardwired electronics. An analog scheme has several disadvantages: nonlinearity of speed sensor, temprature dependency,drift and offset.Once a control circuit is build to meet certain performance criteria,it may require major changes in the hardwired logic circuits to meet other performance requirements.   A microcomputer reduces the size and cost of hardwired electronics,improving reliablity and control performance. This con...

Four Quadrant Chopper Fed DC Motor Drive

Four Quadrant Chopper Fed DC Motor Drive Aim: To study the operation of Multi quadrant Chopper based DC Drive. Learning Objectives: To study the operation of Multi quadrant Chopper based DC Drive. To study Chopper fed DC drive. To study Multi quadrant operations of a Chopper Apparatus : Experimental kit DSO/CRO (Unearthed) Multimeter Patch cords and DSO probes PreTest Theory: There are three basic types of dc-dc converter circuits, termed as buck, boost and buck-boost. In all of these circuits, a power device is used as a switch. Four Quadrant Chopper are widely used for motion-control equipment in the automation industry. Because of significant development of power switching devices, switching frequencies of 10–20 kHz are easily attainable. Chopper Fed DC Drive:                       ...
