Abstract
Boost derived DC-DC converter with multi-cell diode-capacitor/inductor (DCL) network provides a simple solution to achieve high step-up voltage regulation. However, many passive components increase the order and complexity of the system model. By utilizing the difference of the time constant of passive components in the DCL network and the external circuit, this paper proposed the unified reduced-order modeling approach for high step-up DC-DC converters with multi-cell DCL network. Finally, simulation and experiment results verified the correctness of the modeling approach. The measured frequency characteristic is almost consistent with the theoretical calculation from the derived transfer function. The unified reduced-order model contributes to a better understanding of circuit characteristic and simplification of closed-loop controller design.
