A new hybrid Boost-L converter

摘要

The paper proposes a new step-up topology with high step-up conversion ratio. Dc analysis is performed and the static characteristics are derived revealing that the static conversion ratio exhibits a high voltage boost, the converter still operating at reasonable duty cycles. Compared to a classical Boost, the static conversion ratio at the same duty cycle D is (1+nD) time higher, where n is the transformer ratio. Compared to quadratic converters the proposed topology exhibits also one transistor and three diodes, but it contains only one capacitor and only one magnetic device resulting that two reactive elements are eliminated. Design equations are provided and the converter is simulated and experimental tested. The simulation accurately confirmed the theoretical behavior and the experiments where in perfectly agreement with the simulation and theory. This novel converter could be a simple cheap solution in applications where an output voltage much higher than the input voltage is needed.
