In this paper, a single ended primary-inductor converter (SEPIC) is applied for the speed control of DC Motor using the fuzzy logic controller. The fuzzy logic controller is applied to the closed loop system of the DC motor employing the duty cycle control over wide range of speed. The proposed converter uses a single inductor to allow a continuous-conduction mode by making the current never fall to zero. The proposed converter is controlled using the fuzzy logic controller that operates both in buck and the boost operation; unlike the conventional methods the output is non-inverted. The SEPI Converter used is more applicable for the wide range of voltage applications and as it is independent of the input voltage as the average current through the inductor is same as the load current. The proposed method is simulated using the MATLAB program. An experimental verification is done for a DC motor operated by Fuzzy controlled SEPIC and the results are shown.
