This paper introduces eight novel interleaved non-isolated dc-dc converters with ultra-high step-up and zero voltage switching (ZVS) capabilities for renewable energy systems. To increase the voltage gain, the proposed converters benefit coupled inductors, high-frequency (HF) transformer, and voltage multiplier (VM) techniques. In comparison to other converters, which just benefit coupled inductors or HF transformers, these combinations of the techniques make an additional degree of freedom to achieve high voltage gains (more than 25 without extreme duty cycle). Besides, two active clamp circuits, including two stages of switch-capacitor VM cells, not only increase the voltage gain of the proposed converters but also act as an auxiliary circuit to provide ZVS. Moreover, the stored energy in the leakage inductances is absorbed and passed to the output by the clamp capacitors. The input current ripple is reduced by applying the interleaved technique. The voltage stress es across the power switches are clamped to lower values and can be controlled by the turn ratios of the coupled inductors and the HF transformer. The theoretical performance of the proposed converters is fully explained. Also, the proposed converters are compared with more than twenty latest interleaved high step-up and ultra-high step-up dc-dc converters. Finally, a 1 kW, 20 V/500 V laboratory prototype is built to prove the advantages of the proposed converters.INDEX TERMS Interleaved structure, dc-dc converter, ultra-high step-up converter, zero-voltage switching

Summary This paper presents a new voltage multiplier with a small number of components, composed of a coupled inductor and a switched capacitor cell, which allow four different configurations. To evaluate these configurations, these cells were integrated into the boost converter, thus generating four new high voltage gain topologies. These topologies have different characteristics: thus, the principle of operation, voltage gain, voltage and current stress, and design guidelines of each converter were evaluated. Finally, four prototypes of 30 V/400 V and 200 W were built and evaluated experimentally.

This paper presents an ultrahigh step‐up converter with combination of a quadratic boost converter, a multiplier cell, and a three windings coupled inductor. Main advantages of the converter include its high voltage gain, low voltage stress on the switch and most of the diodes, continuity of input current with low ripple, and existence of a common ground between the source and load. Furthermore, requiring small inductors leads to high efficiency performance of the converter. To confirm superiority of the proposed converter, it has been compared with the converters consisting coupled inductors. Analysis of the converter has been performed for its main operation modes to validate its quality and quantity factors. A prototype is built in order to experiment its performance per different conditions and evaluate the analysis. Rated values per the experiments are 25, 500, and 200 W for the input voltage, output voltage, and output power, respectively.
