Abstract
In this article, a nonisolated dc–dc high step-up converter with passive switched-inductor-capacitor network is proposed, which is applicable for the required high-gain voltage low-power applications, such as battery-powered LED lighting systems and high-intensity mobile discharge lamps. The proposed circuit can produce higher gain voltage with small duty cycle, which decreases the voltage stress and conduction power loss on the active switches. In contrast to other nonisolated dc converters, by using the same or analogous number of passive/active components in circuit topology, the proposed topology has lower voltage stresses across capacitors and diodes and lower inductor current stresses. Therefore, the efficiency and reliability of the circuit topology can be ameliorated. The theoretical principle, parameter design guideline, small-signal dynamic analysis, power loss analysis, and performance comparison with other dc–dc nonisolated converters have been implemented. Finally, a 200-W experimental setup is built and tested with an input dc voltage of 36–60 V and an output voltage of 200 V to validate the aforementioned merits of the proposed circuit.
