| Title: | Spurious modulation on current-mode controlled dc/dc converters : an explanation for intermittent chaotic operation | Authors: | Wong, SC Tse, CKM Tam, KC |
Issue Date: | 2004 | Source: | Proceedings of 2004 IEEE International Symposium on Circuits and Systems, May 23-26, 2004, Vancouver, British Columbia, Canada, p. V-852-855 | Abstract: | In this paper, we explain the mechanism that causes "intermittent" instability and chaos in a current-mode controlled switching converter. The circuit model used to study the phenomenon incorporates a coupling process through which a spurious signal is coupled to the current sensing and ramp compensation circuitry, resulting in a modulation of the compensation slope which causes the system to become unstable intermittently. We describe a way to find the parameter boundaries where intermittent chaotic operation emerges. | Keywords: | Switching power converters Current-mode control Intermittent chaos |
