“…The same limitations were found in the research of [17], where a three-level DC-DC boost converter with dual output was presented. An interleaved step-up DC-DC converter topology composed of two boost converters was introduced in [18]. During operation, the converter stages are indirectly connected in a series, which ensures a high voltage gain of the output.…”

This paper introduces a novel converter topology based on an independent controlled double-boost configuration. The structure was achieved by combining two independent classic boost converters connected in parallel at the input and in series at the output. Through proper control of the two boost converters, an interleaved topology was obtained, which presents a low ripple for the input current. Being connected in series at the output, a three-level structure was attained with twice the voltage gain of classic boost and interleaved topologies. A significant feature of the proposed converter is the possibility of independent operation of the two integrated boost converters, in both symmetrical and asymmetrical modes. This feature may be particularly useful in voltage balancing or interconnection with bipolar DC grids/applications. The operation principle, simulations, mathematical analysis, and laboratory prototype experimental results are presented.

In this paper a single-phase boost PFC multilevel interleaved high-voltage gain based on the hybrid switched-capacitor concept is presented. The proposed converter merges interphase transformers and switched-capacitor cells to obtain current sharing and high voltage gain. These features allow for both the reduction of voltage and current stresses on the semiconductors. Furthermore, the interleaving method allows for obtaining multilevel voltages at AC terminals, thereby reducing the weight and bulk of the input inductor. PFC operation is guaranteed through both input current control and output voltage control. Both steady-state and dynamic analyses were conducted. Experimental results for a 1.25 kW, 127 V to 800 V laboratory prototype are presented and discussed.INDEX TERMS High voltage gain, interleaving, interphase transformer cells, power factor correction, PWM rectifier, switched-capacitor.

“…Due to simpler circuitries and unified structures, interfacing multiple sources using MICs results in more efficiency than using several individual single-input converters [3,4]. Various MIC topologies proposed in the literature can be categorised into isolated [5][6][7][8][9][10] and non-isolated structures [11][12][13][14][15][16][17][18][19][20][21][22][23]. In [5,6], sources were connected in parallel using a coupling transformer to supply a common load.…”

This paper presents a battery-integrated multi-input step-up DC-DC converter (BI-MISUC) as a unified interface for multiple energy sources in the frame of a sustainable hybrid energy supply. The proposed converter comprises one bidirectional port for a battery and several unidirectional input power ports. Battery can be charged by input sources, discharged into load or bypassed while charging/discharging durations are independent of switching duty ratios for input sources. In the presented BI-MISUC, higher voltage gains with lower duty ratios are achieved not only by increasing the number of inputs but also using the switched inductor (SI) modules. It therefore enables BI-MISUC to be used for a wide range of applications from low to high voltage/power. Furthermore, input sources can be operated individually or simultaneously to supply load energy at the desired output voltage. The converter operation is described for three scenarios (i.e. no battery, battery charging and discharging). A linear quadratic regulator (LQR) control is also used to regulate the output voltage and output power of input sources at the desired references for different scenarios. Finally, the performance of the BI-MISUC is validated by simulations and experimental results.
