Abstract
This paper contains some experiments based on the paper Chattering Suppression in Multiphase Power Systems by Hoon Lee, Andrey Malinin, and Vadim I. Utkin that will appear in International Journal of Control. In that paper, the use of multi-phase converters and an appropriated phase shift allows reducing chattering to desired level under given switching frequency in the so called “ripple cancelation” or “harmonic cancelation”. Additionally this strategy would consider sliding mode as a suitable substitute over the Pulse Width Modulation because of the benefits in sliding mode control, e.g. the ability to achieve desired system responses regardless of a certain level of parameter changes. A half-bridge buck converter prototype was built and the chattering suppression reported in the Hoon Lee at al. paper has been checked comparing the power converter performances operating with 1-phase and 4-phases respectively.
