In present day situation, the analysis of drive circuits for DC motors are advancing and recent innovative technologies make the system more cheaper and market friendly. The adjustable speed drive system is utilized for speed control purpose of DC motor. In this paper, open loop analysis and output response is studied for a Single phase full bridge rectifier connected to a DC motor feeding from a DC/DC Buck converter. The voltage regulator between two networks make the load voltage adjustable. The Matlab simulation software is used to analyze the system performance and its characteristics under various factors. The performance parameters such as ripple factor, motor and rectifier efficiency, voltage and current THD, and form factors of the system for various firing angles are compared and analyzed. Moreover it is observed that the system output voltage remains constant eventhough there is load and field disturbance in motor. Besides, if the firing angle increases form factor, ripple factor increases whereas the motor efficiency and rectifier efficiency decreases. The main aim of the paper is to prove that the developed model must transmit power with high efficiency and low ripple compared to existing models. The results presented in this paper match with the experimental results.
