Abstract

This paper presents a PI (Proportional-Integral) and SMC (Sliding Mode Control) of a SEPIC converter. The advantage of this method is that it does not need a PWM modulator and only two PI gains are used. The PI gains are calculated through Routh-Hurwitz stability criterion and generalized root loci. To make a comparison, initially the converter is controlled by hysteresis method and subsequently with a fourth and second order Sliding Mode Control before incorporating PI and SMC. The coefficients for SMC have been obtained. The PI and SMC control for SEPIC is then implemented using MATLAB and the results are presented.
