Adaptive Nonlinear Control of Multiphase Synchronous Buck Power Converters
The problem of controlling multiphase synchronous buck power converters is considered. The aim is to regulate the output voltage of the converter and to ensure an adequate current sharing between its different channels. The control law is designed from the large-signal bilinear model (of the whole multichannels converter) using the backstepping technique. The obtained regulator is shown to meet...
متن کاملNonlinear and Adaptive Control of Buck Power Converters
~~ This paper focuses on the problem of controlling DC-to-DC switched power converters of Buck type. The system nonlinear feature is coped with by resorting to the backstepping control approach. Both adaptive and nonadaptive versions are designed and shown to yield quite interesting tracking and robustness performances. A comparison study shows that backstepping nonlinear controllers perform as...
متن کاملRobust Adaptive Wavelet Neural Network Control of Buck Converters
Robustness is of crucial importance in control system design because the real engineering systems are vulnerable to external disturbance and measurement noise and there are always differences between mathematical models used for design and the actual system. Typically, it is required to design a controller that will stabilize a plant, if it is not stable originally, and to satisfy certain perfo...
متن کاملNonlinear Phenomena in Power Electronic: Chaotic Behavior of Buck Converters
Power electronic is rich in nonlinear dynamic. Its operation is characterized by cyclic switching of circuit topologies, which gives rise to different nonlinear behaviors. Among power electronic converters, DC/DC buck converters have been studied with constant-frequency pulse-width modulation feedback control in continuous conduction mode. Time-domain and phase-space plots for several periodic ...
متن کامل“Shoot-through” in Synchronous Buck Converters
The synchronous buck circuit is in widespread use to provide “point of use” high current, low voltage power for CPU’s, chipsets, peripherals etc. In the synchronous buck converter, the power stage has a “high-side” (Q1 below) MOSFET to charge the inductor, and a “Low-side” MOSFET which replaces a conventional buck regulator’s “catch diode” to provide a low-loss recirculation path for the induct...
