A TIME-DOMAIN ASYMPTOTIC APPROACH TO PREDICT SADDLE-NODE AND PERIOD DOUBLING BIFURCATIONS IN PULSE WIDTH MODULATED PIECEWISE LINEAR SYSTEMS

A Time-Domain Asymptotic Approach to Predict Saddle-Node and Period Doubling Bifurcations in Pulse Width Modulated Piecewise Linear Systems

In this paper closed-form conditions for predicting the boundary of period-doubling (PD) bifurcation or saddle-node (SN) bifurcation in a class of PWM piecewise linear systems are obtained from a time-domain asymptotic approach.Examples of switched system considered in this study are switching dc-dc power electronics converters, temperature control
