This paper attempts to implement an elegant Variable Structure Controller (VSC), with a view to regulate the output voltage and improve the power quality of input current of a Single-Ended Primary Inductance Converter (SEPIC) through the use of a DSPIC processor. It aims to exploit the advantages of ease of implementation and robustness of VSC, which facilitates to produce an output that is independent of input voltage, circuit parameters and/or output load. The DSPIC card is designed to perform the function of a VSC, besides serving to generate trigger pulses for the power switches. Simulation and experimental results are presented to demonstrate the merits of the proposed approach.
