Stability analysis of a single inductor dual switching dc–dc converter Original Research Article

This paper deals with the analysis of a single inductor switching dc–dc power electronics converter which is used to regulate two, in general non-symmetric, positive and negative outputs. A PWM control with a double PI feedback loop is used for the regulation of both output voltages. The steady state properties of this converter are first discussed and then stability is studied in terms of both power stage and control parameters.
