“…In fact, the normalized voltage stress across power diodes is low and so the cost of the proposed converter can be decreased by selecting the lower voltage power diodes. In previous studies, although the normalized voltage across power diodes is lower than the proposed converter, it leads to limit the voltage gain of the converter.…”

“…Therefore, the MPPT capability of the converters decreases by increasing the number of input cells. Some new structures of two‐input converters based on the Cockcroft‐Walton (CW) voltage multiplier (VM) cells and modified Dickson charge pump VM cells are presented that their voltage gain increases and the semiconductor voltage stresses decrease by increasing the VM cells. Therefore, the voltage stress across the switches is lower than that of the conventional boost converter.…”

Summary In this paper, a new extendable high step‐up multi‐input‐single‐output dc‐dc converter is presented. The proposed converter is composed based on the conventional boost converter and conventional buck‐boost converter. The benefits of the proposed converter consist of the simple control of each duty cycle and low‐voltage stress across the semiconductors. Therefore, conduction losses can be reduced by using the switch with lower resistance rDS(on). The presented converter is flexible to obtain the high power level with the proper selection of duty cycle values. Therefore, the presented converter is controllable in different power levels of input sides. In fact, the proposed converter supports the operation of multiple input sources without any changes in the structure of the topology. The dynamic modeling and efficient multivariable controller design with dynamic responses for the proposed converter are analyzed completely. To confirm the performance of the presented converter, mathematical analysis and simulation results are presented. In addition, the comparison between the presented converter and some other topologies is provided. In order to illustrate the efficient operation of the presented converter, a laboratory prototype for a 425 V/300 W with 40‐ and 45‐V input voltages and 95.62% efficiency is implemented.

“…To decrease the inductance requirement, the interleaved boost converters based on modified Dickson VMC are proposed in previous studies. [40][41][42] However, large current spikes in the VMC and hard switching operation of the switch contribute more losses. Another type of nonisolated converter that is synthesized by merging a passive switched-capacitor (PSC) network and an active switched-inductor (ASL) network has been proposed in Salvador et al 43 However, it requires two inductors and two switches operating under hard switching condition, which in turn increases the losses.…”

Summary In this paper, a single‐switch hybrid high voltage gain boost converter topology employing zero‐voltage switching (ZVS) feature is proposed. The proposed converter can achieve high voltage gain with soft switching operation over a wide range of load. The topology is a combination of the Cockcroft‐Walton diode‐capacitor voltage multiplier and a conventional boost converter, which results in a hybrid DC‐DC converter. The diode‐capacitor ladder enables the converter to achieve high voltage gain without a transformer or coupled inductor. Because of its transformerless design, single switch with lower duty cycle requirement, and ZVS feature, the efficiency of the converter is improved significantly. Moreover, due to the input inductor, it is able to provide lower input current ripple and variable fractional voltage gain, which is a key requirement for maximum power point tracking (MPPT) in photovoltaic application. A 480‐W hardware prototype with 48‐V input voltage and 450‐V output voltage is developed, and experimental results are presented to validate the efficacy of the proposed converter. The total achievable efficiency is above 95.4%, in the full load range (80‐480 W).

In this paper, a new interleaved DC-DC converter based on a coupled and a single input inductor is proposed. The suggested high step-up converter utilizes various inductive and capacitive methods to transfer magnetic energy more efficiently. The output voltage is regulated with the switches' duty cycle and the coupled inductor (CI) turns ratio, which provide a wide output voltage range. Interleaving improves the converter reliability, employs both the first and third areas of CI's B-H plane, cancels DC component of the CI, and reduces the input current ripple of the proposed converter with twice switching frequency. Utilization of two output ports for voltage stress and ripple reduction in each port, recycling the stored energy of inductances in both forward and flyback mechanisms, alleviation of switch voltage spikes, operation without circulating current, high power density, independency of switch voltage stress to the CI turns ratio, and continuous input current can be mentioned as other features. In this paper, continuous and discontinuous conduction modes' steady-state analytics, power loss calculations, and design procedure of the proposed converter are followed with comprehensive comparisons to evaluate the capabilities. Eventually, experimental results are presented to validate theoretical calculations.
