High-Step-Up Boost Converter Based on Coupled Inductor, Voltage Lift and Clamp Cells

摘要

A high-step-up boost converter based on a coupled-inductor, a voltage lift and a clamp cells is proposed in this paper. The energy stored in the leakage inductances of the coupled inductor is recycled using the voltage lift and the clamp cells to obtain the higher gain. The operation of the proposed converter is explained using ideal waveforms. The effect of leakage inductance is considered in the analysis in addition to the non-ideal behaviour of the semiconductor devices. The operation of the power converter is validated and verified using the simulation and the experimental results. The performance improvements obtained using the proposed solution is compared against the existing converters.
