Nonlinear 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 کاملAdaptive 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 کاملElectrothermal Model of SiC Power Schottky Diodes
The paper concerns the problem of modelling d.c. characteristics of commercial SiC power Schottky diodes with self-heating taken into account. The electrothermal model of the investigated devices is proposed and experimentally verified. The evaluation of accuracy of the elaborated model has been performed by comparison of measured and calculated characteristics of selected SiC power Schottky di...
متن کاملSiC-BASED POWER CONVERTERS
The advantages that silicon carbide (SiC) based power electronic devices offer are being realized by using prototype or experimental devices in many different power applications ranging from medium voltage to high voltage or for high temperature or high switching frequency applications. The main advantages of using SiC-based devices are reduced thermal management requirements and smaller passiv...
متن کاملDC-DC Power Converters
Dc-dc power converters are employed in a variety of applications, including power supplies for personal computers, office equipment, spacecraft power systems, laptop computers, and telecommunications equipment, as well as dc motor drives. The input to a dc-dc converter is an unregulated dc voltage Vg. The converter produces a regulated output voltage V, having a magnitude (and possibly polarity...
