Week-7 Challenge: DC Motor Control

1. A. Explain a MATLAB demo model named ‘Speed control of a DC motor using BJT H-bridge’. This model shows the simulation of an H-bridge used to generate a chopped voltage and to control the speed of a DC motor. Here the power BJT switches act as chopper & by varying the duty cycle of the switches…
