Fuzzy Logic Based Adaptive Controller for AC/DC Boost Converters

Inhalt:
AC/DC digital boost converters often implement bus voltage regulation emulating analog controllers. This approach although presenting several advantages has the disadvantage to be computationally expensive. This paper presents a fuzzy logic based adaptive controller for bus voltage regulation. The paper highlights the lean computation of the fuzzy controller and shows comparative results to a standard analog controller. Simulations confirm the suitability of the proposed methodology for AC/DC boost converters in particular for cost sensitive applications such as lighting.
