This paper presents a strategy for using SEPIC in BLDC motor in Discontinuous Conduction Mode (DCM), which is often advised for low-power applications. Using three interleaved SEPIC converters, this is possible. Because the power is distributed among the interleaved modules, the proposed design reduces stress on the semiconductor components. By considering both capacitance and inductor current, the design handles DCM functioning (DCVM and DICM, respectively). In this study, the proposed converter's analysis examined. In addition, the effectiveness of the converter is measured. Component count is lowered by using coupled inductors, which minimize input ripple current, lower switching losses, less total harmonic distortion (THD), and greater resistance to duty cycle mismatches. High torque/inertia ratio, efficiency, robustness, and low EMI (electro-magnetic interference) are some of the advantages of BLDC motors. Matlab/Simulink software is used to implement the proposed approach.
