“…As can be noted, the static gain of the proposed converter is higher than those obtained from the converters proposed in [2, 10, 18, 31] for the whole duty cycle range. In addition, it is equal to the static gain of the converter proposed in [19] and lower than the static gain of the converter derived in [30].…”

“…This section compares the proposed converter with other high‐gain non‐isolated structures previously presented in the literature, including ASL‐SU2C [10], SL/SC‐ANC [19], Cuk‐boost converter [29], non‐coupled inductor SEPIC converter [18], extendable active–passive inductor cell converter [2], the SC‐based converter [30] and ASL‐SU2C‐VO [31].…”

“…The converter ASL‐SU2C [10], ASL‐SU2C‐VO [31] and the converter derived in [18], have less number of components than MASL‐SC but present lower static gain and higher voltage stress on the switches. It is important to highlight the input currents of the converters proposed by the authors of [18, 29] are constant, while in the MASL‐SC, it is pulsed, due to the MASL.…”

Independent Double-Boost Interleaved Converter with Three-Level Output

et al. 2021

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.

“…Switched-inductor and active switched-inductor structures can charge the inductors in parallel and then discharge them in series to obtain a higher voltage gain. The proposed structure is amenable to many other structures [16], [17]. Unfortunately, the input current has become discontinuous.…”

Conventional dc-dc Boost converter has limited boost capacity, and its power device suffers high voltage stress. A novel Z-source based dc-dc boost converter featured with high step-up capability and low device voltage stress is proposed in this paper. The proposed topology can also provide a common ground for input and output, which is lacking in the traditional Z-source topology. Compared with other high step-up topologies, the proposed converter can achieve higher voltage gain under the same duty ratio and maintain low voltage stresses on the switch and diode. Moreover, there are fewer passive components in the proposed structure than in other structures. The steady-state analysis for the continuous conduction mode and discontinuous conduction mode is also provided in this manuscript. Finally, a prototype circuit with 40V-60V input voltage, 400V output voltage and 200W output power is implemented in the laboratory. Experiment results confirm the analysis and the features of the proposed converter.
