Abstract

In this paper, implementation of zero current switching for high step-up full bridge isolated dc-dc converter with multi-cell diode capacitor network. The converter's is used to increase the low input voltage to a higher output voltage that can be used in a variety power application. The proposed network consists of a boost converter and a ZCS realization circuit that regulates the output voltage by adjusting the duty cycle of the boost converter. The results demonstrate that the proposed converter provides a high step-up ratio and a stable output voltage with low ripple. It has the following advantages increases voltage boost capability and avoid extreme large duty ratio, achieves almost zero output voltage ripples, reduces transformer turns ratio. furthermore, zero current switching (ZCS) Realization helps in increases the efficiency and decreases the switching losses which caused by the voltage stress and distortions. The PI controller results provides a high step-up ratio and a stable output voltage with low ripple. The closed-loop control system also shows excellent dynamic performance with fast response to load and input voltage changes. Overall, the proposed converter offers an efficient and reliable solution for high voltage applications.
