Abstract
DC-DC converter commonly used in photovoltaic systems, fuel cell systems and electric vehicles is a boost converter. The interleaved boost converter, connected in parallel by several boost converters and operated by the phase difference to reduce the input and output current ripple, has been widely used in recent years. Because of small input and output current ripples, the circuit can reduce the size of the input and output capacitors. Thus, instead of conventional electrolytic capacitor, the film capacitor with high reliability can be used and this is the life and reliability of the entire system can be improved. In this paper, the output current ripple formulas of the multi-stage interleaved boost converter are derived, and the characteristics in accordance with duty are found out. In order to verify the abovementioned contents, the derived results will make a comparison with the calculated values by using PSIM tool.
