Abstract:
|
In this paper, instabilities and bifurcation behavior in a DC–DC digitally controlled voltagemode
synchronous buck converter (SBC) are studied. The bifurcation diagram of the system
under a proportional-integral (PI) compensation is presented. Following the system mathematical
description in the continuous time domain, the z-domain pulse transfer function is derived
in terms of system parameters. The stability range of the design parameter is obtained in closed
form by using the Jury test combined with the describing function (DF) method. Experimental
measurements from a laboratory prototype are used to validate the theoretical predictions and
the numerical simulations. |
