Abstract :
Intermittent phenomena are commonly observed in periodically driven switching power converters. This paper explores the intermittent chaos and subharmonics in a current-mode controlled SEPIC converter using a circuit model with intruding interference. The theoretical analysis and computer simulation are prensted, which indicate that the signal strength and frequency of the intruding interference are vital parameters that affect the type and the period of intermittency.
