“…(4) The energy conservation produces that since the output voltage is larger than the input voltage, with a voltage gain given by Equation ( 17), the input current is larger than the output current with the same proportion. This can be observed from Equation (15), the dc input current is the same as I L1 since the capacitor C 1 cannot drain dc current.…”

“…There are quadratic types of topologies in the state-of-the-art that perform switching ripple cancelation, in which series capacitors have shifted voltage ripple, for example, [15,16], in that case, those converters require at least two transistors and a particular PWM (Pulse-Width Modulation) strategy.…”

This work presents a power-electronics based system for renewable energy applications, the system is driven with an only one switch quadratic type boost converter, the discussed converter is based on a stack of switching stages which provide a large voltage gain, a desirable feature for fuel cell generation systems, the converters gain function is the quadratic boost-type converters; furthermore, the topology can be extended. The major benefit of the topology is that there is not a capacitor that sustains the entire output voltage, in contrast to other similar topologies in which there is a capacitor rated to the output port voltage, there is no high voltage capacitor in this system. Experimental verification is presented to confirm the system principles; experiments included a fuel cell emulator that was built and used for the experiments.

A Non-Inverting High Gain DC-DC Converter With Continuous Input Current

et al. 2021

High gain DC-DC converters are increasingly being used in solar PV and other renewable generation systems. Satisfactory steady-state and dynamic performance, along with higher efficiency, is a pre-requirement for selecting the converter for these applications. In this paper, a non-inverting high gain DC-DC boost converter has been proposed. The proposed converter has only one switch with continuous input current and reduced voltage stress across switching devices. The operating range of the duty cycle is wider, and it obtains a higher gain at a lower value of the duty cycle. Moreover, the converter has higher efficiency at a lower duty cycle while drawing a continuous input current. The continuous input current is a desirable feature of the dc-dc converter making it suitable for solar photovoltaic applications. The converter's operation has been discussed in detail and extended to include the real circuit parameters for a practical performance evaluation. The proposed converter has been compared with other similar recently proposed converters on various performance parameters. The loss analysis for the proposed converter has also been carried out. Finally, the simulation has been validated with results from the experimental prototype.INDEX TERMS Continuous conduction mode, duty cycle, high gain, DC-DC boost converter, voltage stress.

“…In literature, quadric boost, 18–22 quadric buck, 23,24 and buck‐boost converters 25–27 reported either use a higher number of passive elements or cannot handle complementary switching. A single switch cascaded boost and buck‐boost converter proposed in Fu et al 28 has a drawback of floating and discontinuous nature of the output.…”

Summary In this paper, two cascaded buck‐boost nature converters are developed; one converter is capable of producing high step‐up gain, and the other converter addresses high step‐down gain. In proposed converters, for a given voltage gain, two distinct duty ratios are possible due to their ability in handling complementary switching schemes. This feature is effective for voltage‐sensitive applications like LED systems. The operation principle, steady‐state analysis, and the design of the passive components for each switching scheme are presented for the proposed converters. Comparative analysis with competitive converters profound the merits of the proposed converters in terms of voltage gain and the continuous nature of the output. Experiments are conducted on both proposed converters for simultaneous and complementary switching schemes, and they validate the theoretical steady‐state performance.
