Current ripple bounds in interleaved DC-DC power converters
In distributed power supply systems, the parallelism of DC-DC power converters is a basic architecture. In this paper, the authors use the time domain method to show that the amplitude of the input/output current ripple of N(/spl ges/1) parallelly interleaved modules is always upper bounded by that of the individual modules for buck, boost, flyback, Cuk, and SEPIC power converters if the phase shift among the modules is 2/spl pi//N. Efficient numerical algorithms for predicting the net ripple amplitude in interleaved power modules are derived based on the insight gained from the time domain method.<>
