Abstract :
The authors have devised a nonlinear coordinate transformation for a DC-to-DC buck chopper supplying a constant power load that facilitates pseudolinearization via a nonlinear feedback. A representative design is introduced and detailed simulation validation studies are presented. The extension of the region of local asymptotic stability is confirmed through Lyapunov analysis
