“…As can be observed, the proposed converter has a higher voltage gain than the conventional interleaved boost converter and the converters presented in [42,43]. The interleaved converter, which is presented in [44], has a higher voltage gain in duty cycles below 0.4. However, in duty cycles higher than 0.4, which is favourable in high step-up applications, the voltage gain of proposed converter goes out the voltage gain of [45].…”

A new interleaved boost converter with high step-up gain is presented in this paper. The proposed topology integrates coupled inductors and floating-output capacitors technique into interleaved boost converter to provide high step-up voltage gain without extreme duty cycle. The voltage stress on the power switches and diodes is very low, so low-cost and highperformance semiconductor devices can be employed. Also, the reverse recovery problem of all diodes is mitigated and zero-current-switching (ZCS) turn-on operation of the main switches is established as well. In addition, the passive clamp circuits are employed to suppress the voltage spikes across the main switches during turn-off instants. The operating principles and steady-state analysis of the proposed converter in continuous condition mode are explained. Finally, the simulation and experimental results of prototype 25-400 V circuit with 200 W output power are provided to verify the performance of presented topology.

“…The literature [5][6][7][8] proposed a built-in transformer unit circuit (Built-In Transformer Cell, BITC) high gain converter, but in order to eliminate the voltage spikes of the switch, the need to increase the absorption circuit, increasing the complexity of the circuit. The literature [9][10][11] proposed a cascade high gain converter, in the post-converter using coupling inductance technology, can effectively achieve the converter's high gain characteristics [12][13] , but the converter cascade will lead to low efficiency.…”

Abstract. When the traditional Boost converter duty cycle exceeds a certain value, the output voltage is not only increased, but will be reduced. Therefore, a new Boost converter with intermediate tap is proposed. By replacing the ordinary inductance of the traditional Boost converter with the inductance with the intermediate tap, the theoretical comparison is made with respect to the traditional boost converter. Under the same duty cycle, The Boost converter has a significant high gain ratio. Finally, the simulation and experimental analysis of the proposed new Boost converter are carried out by simulation software Pspice. The experimental results show that the new Boost converter has a significant high gain ratio compared with the traditional boost converter.

“…Single-stage topology incorporates coupled inductors and/or switched capacitors to complete high voltage gain. Even though its input voltage is boosted, a large magnitude of input current ripple occurs, limiting the converter power rating significantly [5][6][7][8]. The interleaved converter has the ability of suppressing input current ripple by means of adding a parallel current path, which is a better choice for high power applications [9][10][11].…”

This paper presents a novel interleaved converter (NIC) with extra-high voltage gain to process the power of low-voltage renewable-energy generators such as photovoltaic (PV) panel, wind turbine, and fuel cells. The NIC can boost a low input voltage to a much higher voltage level to inject renewable energy to DC bus for grid applications. Since the NIC has two circuit branches in parallel at frond end to share input current, it is suitable for high power applications. In addition, the NIC is controlled in an interleaving pattern, which has the advantages that the NIC has lower input current ripple, and the frequency of the ripple is twice the switching frequency. Two coupled inductors and two switched capacitors are incorporated to achieve a much higher voltage gain than conventional high step-up converters. The proposed NIC has intrinsic features such as leakage energy totally recycling and low voltage stress on power semiconductor. Thorough theoretical analysis and key parameter design are presented in this paper. A prototype is built for practical measurements to validate the proposed NIC.
