In this paper, a non-isolated high step-up interleaved DC-DC converter for distributed generation applications such as solar cells and fuel cells. The proposed converter mixes the benefits of magnetic coupling, voltage multiplier, and voltage lift techniques to conventional interleaved schemes. The proposed converter's voltage lift technique can increase the voltage gain while guaranteeing low voltage stress of the switches. And the magnetic coupling method can combine the switched capacitor of the voltage multiplier technique with the lossless clamp circuit to achieve high voltage gain and reuse the leakage inductance energy to the output terminal. In addition, this leakage inductance energy can achieve zero current switching turn on soft switching performance and mitigate the output diode reverse recovery problem. The proposed converter avoids the extreme duty cycles that cause conduction losses in power devices and can give very low voltage stresses. Therefore, the use of low voltage rated MOSFETs and diodes not only reduces switching losses and costs, but also improves efficiency. INDEX TERMS High voltage gain, magnetic coupling, non-isolated, voltage lift (VL) technique, zero current switching (ZCS).

“…Main circuit parameters were selected for the application use within photovoltaic systems, where proposed converter solutions shall be used as MPPT converter, which shall distribute energy within other power semiconductor converter subsystems or shall operate as energy charger for storage components (Figure 12). Also, these parameters have been selected due to the ability of photovoltaic panels which are connected in series, while their output voltage is reaching 120 V [38]. Since the converter system considers microgrid operation its power rating was initially set to 500 W, while it is not excluded that other variations of input/output parameters are not possible.…”

In this article, design, analysis, and experimental testing of a dual interleaved boost converter with coupled inductor including demagnetizing winding are presented. Proposed topology uses the specific design of boost coils placed within the side parts of the EE core together with a demagnetizing coil located on the center part of the core. Paper describes principles of operational scenarios and characteristics. Through modification of turns ratio between boost coils and demagnetizing coil is possible to achieve high voltage gain. Consequently, the functional performance of this perspective topology is realized experimentally. For that purpose, the physical sample of converter is designed and tested in terms of efficiency considering the change of transferred power or the change of input voltage. Through modification of turns ratio between boost coils and demagnetizing coil is possible to achieve high voltage gain, therefore these dependencies are also evaluated considering also the change of the duty cycle. At the end of the paper basic operational properties are compared to standard boost topologies. It was discovered that even due to higher complexity of the proposed converter oppose to selected topologies, the operational performance is much better considering ripple of the electrical variables, efficiency, or the size of circuit components.

Interleaved High Step-Up DC-DC Converter Based on Voltage Multiplier Cell and Voltage-Stacking Techniques for Renewable Energy Applications

A novel interleaved high step-up DC-DC converter based on voltage multiplier cell and voltage-stacking techniques is proposed for the power conversion in renewable energy power systems. The circuit configuration incorporates an input-parallel output-series boost converter with coupled inductors, clamp circuits and a voltage multiplier cell stacking on the output side to extend the voltage gain. The converter achieves high voltage conversion ratio without working at extreme large duty ratio. The voltage stresses on the power switches are significantly lower than the output voltage. As a result, the low-voltage-rated metal-oxide-semiconductor field-effect transistors (MOSFETs) can be employed to reduce the conduction losses and higher conversion efficiency can be expected. The interleaved operation reduces the input current ripple. The leakage inductances of the coupled inductors act on mitigating the diode reverse recovery problem. The operating principle, steady-state analysis and design guidelines of the proposed converter are presented in detail. Finally, a 1-kW prototype with 28-V input and 380-V output voltages was implemented and tested. The experimental results are presented to validate the performance of the proposed converter.
