Abstract
In many applications of aeronautics, telecommunication and Electric Vehicles, such as the headlight, audio of Electric Vehicles and communication power supply, a high voltage conversion ratio is needed to obtain the required operating voltage. Usually, the converters are designed to work stably alone. However, the interaction among individual converters may lead to an instability of the whole system, thus, the stability analysis of cascaded DC-DC converters is a hot issue. In this paper, a time-domain stability analysis method with good extensibility for cascaded DC-DC converters is proposed. At the beginning, the stability criterion for cascaded DC-DC converters is derived by taking N-cascaded buck converters as an example. Further, 3-cascaded buck converters system is studied as a concrete object and the theoretical analysis results based on the proposed method are obtained. Finally, the accuracy of the proposed stability analysis method is verified by simulation and experimental results. Therefore, a concrete and effective stability analysis method with good extensibility is provided for cascaded DC-DC converters in this paper.
