“…Because high step‐up capability is of interest, only [0.5‐0.95] range of duty cycles is considered. Figure shows the voltage gain of the proposed and Miao et al, Banaei and Bonab, Zhou et al, and Li et al topologies. It is observed from Figure A that for wide range of d 1 and d 2 , the proposed topology and Li et al produce higher voltage gains, in comparison with other references.…”

“…A transformerless buck‐boost converter with simple structure and positive output voltage polarity has been presented in Miao et al Another buck‐boost topology with only 1 switch has been presented in Banaei and Bonab . Both Miao et al and Banaei and Bonab are not capable of BPF operation. Also, due to discontinuous characteristic of input currents, these 2 topologies cannot perform MPPT in PV or wind turbine applications.…”

Summary This paper proposes a modular nonisolated noncoupled inductor‐based high‐voltage gain multi‐input DC‐DC converter. Despite the high‐voltage gain of the proposed topology, the average of normalized voltage stress (NVS) on its switches/diodes is low. This property leads to less loss and cost of switches/diodes. Using the same number of components, the proposed topology produces higher voltage gains, in comparison with recently presented high step‐up topologies. Also, the proposed topology utilizes less number of components (capacitors, inductors, diodes, and switches) for producing a desired voltage gain, which can reduce the size, mass, cost, complexity, and losses and improve the efficiency of converter. Continuous current of input sources is another main advantage of the proposed topology. All the abovementioned characteristics have made the proposed topology very suitable for renewable energy systems (or even hybrid/electric vehicles). Design considerations of the proposed topology have also been presented. For better evaluation, the proposed topology has been compared with some of recently presented high step‐up structures, from viewpoints of producible voltage gain, number of components, and normalized voltage stress (NVS) on switches/diodes. Finally, the prototype of 2‐input version has been experimentally implemented. Obtained experimental results confirm appropriate performance of the proposed topology.

“…6 Piezoelectric actuators are considered an alternative because they can produce micro-level deflection with large force generation, fast response, and long-term actuation compared to other actuators. 2,7 In the field of high power, there are other circuit topologies with higher step-up ratios and better control strategies to drive piezoelectric actuators, [8][9][10] but these topologies often mean larger volume and more complex control methods that will limit them to be applied in micro mobile robot. So, micro converters are investigated to boost the low voltage energy source.…”

In this study, a micro converter for driving a piezoelectric actuator is designed and implemented. The converter can produce 100 V, 80 Hz AC voltage from 3.7 V DC voltage. With regard to the requirements of micro mobile robots, the main contributions of this study are the design and implementation of a circuit topology supplying power for micro mobile robots at low power and the miniaturization of this topology to make it suitable for driving a centimeter-level robot. The 91 mg mass (excluding printed circuit board mass), 14 Â 12 Â 4 mm size, and 84.6% efficiency of the converter indicate that this circuit could be applied in micro mobile robots driven by piezoelectric actuators.

Summary This paper presents the design and development of an improved high‐gain buck‐boost converter (HGBBC) with optimized Type III controller suitable for power supplies in various electrical/electronics devices. The proposed HGBBC produces higher efficiency, exhibits better performance, is less bulky, and is compact in size. The voltage gain of the proposed HGBBC is the squared times the voltage gain of the conventional buck‐boost converter (BBC). The polarity of source and load (output) voltages are the same (ie, noninverting polarity). This added advantage of the proposed converter allows it to operate the positive load voltage variation in a wider range even with small variation of duty cycle ratio of the power switches. Therefore, its application may be advantageous for electronics/electrical equipment. The proposed converter's validity is determined by its steady‐state analysis, small‐signal analysis, and closed loop control operation. A closed‐loop controlled of HGBBC utilizing optimized Type III controller has been fabricated and tested in the laboratory. The comparative studies in terms of efficiency, dynamic response, and percentage ripple content of the proposed HGBBC and existing converters have been performed. From the results, it is seen that the proposed HGBBC is performed better than other existing quadratic types of BBCs.
