“…Simultaneous power transfer adds flexibility when an input source alone is not able to feed R o power. Simultaneous power transfer capability in all converters and independent power transfer can be seen in converters of [12], [14], [17], [19], and [21]. The number of elements used in the proposed converter is the same as the number of converter elements in [16] and [18].…”

A new triple‐input DC–DC converter with bidirectional ability is proposed in this paper. This converter is an interface between two unidirectional ports, one bidirectional port for the battery, and a DC link. This makes the proposed converter suitable for hybrid energy systems (HES). The load power can be provided by each input source separately or simultaneously. Also, the battery can be charged by input sources as well as with the energy returned from the output. These features provide a high degree of flexibility for the proposed converter. Boost and buck‐boost operation and low‐voltage stress on semiconductors are other advantages of the proposed converter. The performance of the converter in continuous conduction mode (CCM) is given along with the governing mathematical equations. The experimental results on a laboratory prototype confirm the theoretical calculations.

“…The switches are isolated from one another [17]. The converter is made up of four-unit cells, each of which includes a DC voltage source, a transistor as a switch, and a diode [18]. Limited the number of phases to four (N=4) as an illustration rather than a limitation, in order to keep the diagram simple and sufficiently discuss the paper's methodology in depth.…”

In the current digital environment, central processing unit (CPUs), field programmable gate array (FPGAs), application-specific integrated circuit (ASICs), as well as peripherals, are growing progressively complex. On motherboards in many areas of computing, from laptops and tablets to servers and Ethernet switches, multiphase phase buck regulators are seen to be more common nowadays, because of the higher power requirements. This study describes a four-stage buck converter with a phase shedding scheme that can be used to power processors in programmable logic controller (PLCs). The proposed power supply is designed to generate a regulated voltage with minimal ripple. Because of the suggested phase shedding method, this power supply also offers better light load efficiency. For this objective, a multiphase system with phase shedding is modeled in MATLAB SIMULINK, and the findings are validated.

A battery integrated multiple input DC-DC boost converter

In this paper, the proposed single boost converter aims to harness more than one renewable energy (RE) input source and achieve a high voltage gain. The interleaved technique combined with voltage multiplier (VM) cells, reduced inductor current and attained high voltage transfer ratio. The boost converter possesses two unidirectional input ports and a bidirectional input port that is connected to a battery storage. The duty ratios of the power and interleaving switches are used to regulate the output voltage of the proposed converter. Three operation modes are identified, and steady state analyses of the converter are presented and discussed. The converter can store excess energy in the battery during periods of abundance and deliver power to the loads when the RE sources are low or unavailable. In addition, the output voltage is higher than that of the conventional boost converter. The converter delivered 278 V from 12 V and 24 V dual input sources. The converter operation is simulated and verified using MATLAB/Simulink.
