“…To overcome these shortcomings, researchers have been encouraged to use the higher order PRTs, such as fourth-order and fifth-order topologies. [20][21][22] Although the high-order PRT analysis is more complicated, the significant variety of topologies, lower sensitivity to parameters variation, better controllability with narrower frequency variation due to the sharper frequency response, and higher capability in utilization of the LRC parasitic components make them an attractive alternative for high performance applications.…”

“…For taking advantage of this method in LRCs, the PRT must have the immittance property in the switching frequency.

[13][14][15] The order and arrangement of the reactive components in the PRTs are very important and have a significant effect on the converter operation.…”

Passive resonant tanks (PRTs) with immittance property are suitable candidates to achieve constant output current in load resonant converters (LRCs). In this paper, fifth-order Π-type LC networks are investigated to accede this target. At the first step, fifth-order Π-type passive LC networks that can be applied as a PRT are specified based on source and sink natures. Also, their structural advantages are described in detail to give a suitable perspective for the topology selection. At the second step, immittance property is verified for the proposed topologies and immittance PRTs (IPRTs), with their immittance operation conditions, are derived. To confirm the effectiveness, a 150-W LRC is implemented leveraging new Π-type IPRTs. A deep investigation is devoted to analyze the current/voltage stress in the components of the designed LRC. Moreover, kVA/kW ratio is considered as a key parameter for the reactive component size minimization. The proposed constant current LRC presents high load regulation capability in addition to the minimum reactive power and zero-voltage switching (ZVS) on the inverter MOSFETs under the various loads. A significant robustness against load variations, less sensitivity versus parameters variation, and relatively higher efficiency are the main superiorities of the fifth-order IPRTs to the lower order counterparts.

“…DC-DC converters of a hybrid solar-wind energy system need an efficient power conditioning system to operate the converter efficiently and economically along with the capability to extract the maximum power from each of the renewable energy sources [23][24]. Solar panel and wind generator are distinct in term of the nature of the sources, availability of power and loading factor of the system.…”

-This paper proposes the modeling and control strategy to track the MPPs of hybrid PV and Wind power systems, using a new dual input boost converter. The dual input power conditioning system with an independent MPPT control scheme is introduced with minimum number of circuit elements in order to reduce the switching loss, size and cost of the system. Since the operating conditions for the PV and Wind power systems are very distinct from each other, an efficient and superior control system is required to track the MPPs of both renewable sources with the use of a simply-structured single-ended single-inductor converter. The design of Power-Conditioning System (PCS) and detail control strategy are presented in this paper. To provide independent tracking of MPPs, a variable duty-cycle control strategy is employed for the wind system and a variable frequency strategy is employed for the PV system. Finally, the proposed dual-input converter for hybrid power conditioning system is implemented and the hardware test results are presented. From the hardware experiment, it is concluded that the proposed system successfully tracks the MPPs of both of the renewable power systems independently.

“…The forward converter is based on the buck topology; the flyback converter is based on the buck-boost topology; Full-bridge as well as Half-bridge converters can be both buck and boost derived. Moreover, converter types can be classified based on transformer core utilization [16]. Forward and flyback topologies have a net DC current in the transformer winding, which means the flux in the core must be reset at the end of each switching cycle.…”

A New Efficient Step-Up Boost Converter with CLD Cell for Electric Vehicle and New Energy Systems

An increase in demand for renewable energy resources, energy storage technologies, and electric vehicles requires high-power level DC-DC converters. The DC-DC converter that is suitable for high-power conversion applications (i.e., resonant, full-bridge or the dual-active bridge) requires magnetic transformer coupling between input and output stage. However, transformer design in these converters remains a challenging problem, with several non-linear scaling issues that need to be simultaneously optimized to reduce losses and maintain acceptable performance. In this paper, a new transformer-less high step-up boost converter with a charge pump capacitorand capacitor-inductor-diode CLD cell is proposed using dynamic modeling. The experimental and simulation results of the proposed converter are carried out in a laboratory and through Matlab Simulink, where 10 V is given as an input voltage, and at the output, 100 V achieved in the proposed converter. A comparative analysis of the proposed converter has also been done with a conventional quadratic converter that has similar parameters. The results suggest that the proposed converter can obtain high voltage gain without operating at the maximum duty cycle and is more efficient than the conventional converter.
