Design And Construction Of Dc To DC Chopper Trainer

ABSTRACT

 The speed of separately excited DC motor can be controlled from below and up to rated speed using chopper as a converter. The chopper firing circuit receives signal from controller and then chopper gives variable voltage to the armature of the motor for achieving desired speed. There are two control loops, one for controlling current and another for speed. The operation of a chopper was done, so also the construction of a chopper based trainer (training module). The complete layout of DC drive mechanism is obtained. The designing of current and speed controller was carried out. After carrying out the laboratory test and analysis, it was found that the measured result was in accordance with the expected result. Hence the project was confirmed okay
