“…When S1S2=11, C1 and C2 are in the discharging state, the capacitances of C1 and C2 can be deduced as (25), in terms of Fig. 2(c) and Fig.…”

“…A family of diode-coupled-winding Boost DC-DC converters with a high voltage-gain can perform better than their active-clamp counterparts due to recycled leakage energy [24], achieving a maximum efficiency about 91.7%. Based on [23] and [24], a high voltage-gain interleaved Boost DC-DC converter magnetically coupled to a voltage-double circuit was proposed in [25]. In addition, another high voltage-gain Boost DC-DC converter can obtain higher efficiency, which is based on the three-state commutation cell with additional two transformers (six windings) [26].…”

A Wide Input-Voltage Range Quasi-Z-Source Boost DC–DC Converter With High-Voltage Gain for Fuel Cell Vehicles

“…The theoretical duty cycle of the power switch can be adjusted from 0 to 1, so the voltage gain can be infinite [8], [9]. However, due to the presence of parasitic elements in the circuit, the voltage gain is limited [10], [11]. In addition, the voltage stress of the power switch is as large as the output voltage, and this demands a high-voltage-rated power switch when the output voltage is high.…”

An Original Transformer and Switched-Capacitor (T & SC)-Based Extension for DC-DC Boost Converter for High-Voltage/Low-Current Renewable Energy Applications: Hardware Implementation of a New T & SC Boost Converter

“…To operate the DC-DC converters for getting high output voltage without using high duty cycles for power semiconductor controlled switches, isolated converters can be employed which contain transformers, coupled inductors, etc. [29][30][31][32][33][34][35][36][37], but the usage of such a large number of magnetic components increases the size of the circuit as well as the leakage reactance of the converter and also produces electromagnetic interference which reduces the converter function ability and efficiency. Recently many boost converter topologies are addressed by extending the power circuit of the traditional boost converter.…”
