Title
A Wide-Stable-Region Logarithm-Type Slope Compensation for Peak-Current-Mode Controlled Boost Converter
Abstract
When a peak-current-mode controlled (PCMC) boost converter operates at <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$D&gt;0.5$ </tex-math></inline-formula> , instabilities such as bifurcations and chaos severely restrict its operation range. This brief proposed a logarithm-type slope compensation (LTSC) to use small amplitude signal to provide enough compensations. Firstly, with the aim of minimizing the error magnification of the input current, the proposed LTSC is deduced. Secondly, the comparisons between the proposed LTSC and other slope compensation (SC) methods are made. Finally, simulations and experiments are carried out to verify the theoretical analysis. The research offered a novel SC to suppress instabilities in PCMC boost converter when <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$D&gt;0.5$ </tex-math></inline-formula> . The proposed LTSC has advantages such as: (1) LTSC uses smaller amplitude to stabilize the converter; (2) LTSC extend the stable region of boost converter; (3) LTSC can be applied in other PCMC dc-dc converters.
