Abstract

In this paper, stability of the Luo converter and the effect of circuit elements on the stability and damping fluctuation frequency is investigated. Along with this, the mathematical modeling of positive output (P/O) Luo converter in continuous conduction mode (CCM) is done by using an average state-space method. By using the obtained mathematical model, the transfer function of the Luo converter is extracted, and by using the location of the roots the mentioned transfer function, stability, and effect of circuit elements on converter behavior are studied. Also, its situations are compared with other converters. The analyses are performed through MATLAB based on simulations, which includes both roots location and bodes diagram.
