“…The voltage gain and efficiency comparison of the conventional and proposed DC–DC converters are illustrated in Figure 19. The statistical analysis of the proposed DIMO DC–DC boost reveals that the proposed converter offered high boosting gain with a low duty ratio than the other traditional converters presented in References 3,16,19‐21. The presence of more passive and active reduces the conversion efficiency of the proposed DMIMO converter.…”

Summary In this paper, a novel solar‐powered dual‐input multiple‐output (DIMO) DC–DC converter is proposed to feed the power demanded by the grid‐connected three‐phase three‐level (TPTL) T‐type inverter. The concept is to utilize the two coupled inductors, four capacitors, and one three‐winding high‐frequency transformer. The converter is designed to accept two different inputs and to provide three outputs. Two of its output ports are utilized to charge the two battery banks and another one is used to provide the power for the TPTL T‐type inverter at the required level. The coupled inductors and capacitors are made to discharge their stored energy in series with the primary of the three‐winding high‐frequency transformer to achieve high step‐up voltage gain. Besides, fuzzy logic controller (FLC)‐based DC‐link voltage controller and Synchronous Reference Frame (SRF) theory controllers are incorporated to reduce the ripple content in the DC and AC voltages. The different operating modes and steady‐state analyses are presented. Finally, the results of simulated and experimental prototype models are presented to verify the boosting ability and efficiency of the proposed converter.

SummaryThis study describes a three‐phase six‐level (TPSL) inverter‐based dynamic voltage restorer (DVR) that employs a newly designed isolated multi‐port interleaved flyback converter (IMPIFC). A conventional DVR needs a big and heavy series transformer even for a three‐phase low‐voltage system, which is rated up to 400 V. Power electronic engineers have developed high‐frequency isolated DC–DC converters as a result of the introduction of advanced semiconductor devices and magnetic cores. Control and performance of a low‐voltage DVR utilizing a high‐frequency isolated DC–DC converter are discussed. In the proposed IMPIFC, the high‐frequency (25 kHz) transformer, which is smaller in size than the line‐frequency transformer, is utilized to reduce the size and to integrate multiple energy sources together. In addition, the introduction of a TPSL inverter into the configuration of DVR considerably reduces the injection of harmonic components into the distribution network. The proposed structure of DVR is named as “TPSL‐DVR.” The experimental findings of a three‐phase, three‐wire, 400 V, 50 Hz, 2kW laboratory system validate the boosting ability, feasibility, and efficiency of the system layout.

“…During the blustery days the PV system offers low direct current (DC) output voltage. To regulate and boost the output voltage of the PV system, wants a front end converter to step-up the input voltage to the level required for the synchronization [4][5][6][7][8]. In the recent years, many researchers are worked on the development of new and efficient power converters and boost converters to reduce the volume and weight [9][10][11][12].…”

In this paper, a photovoltaic (PV) tied modified three-port active flyback converter (MTPACFC) operated three-phase micro-inverter is presented to provide enhanced voltage gain with fewer components. The proposed micro-inverter transfers the power generated on the 12 V PV power generation system to 400 V, AC grid. Generally, the DC-DC converter designed with an active clamp circuit provides improved power transfer capability to transfer the power from the PV array. The conventional active clamp flyback converters are designed to offer a limited boost factor for the input voltage. The recommended three-port altered flyback converter is intended to offer double boosting for the input voltage with extended performance. Besides, a synchronous reference frame theory with an artificial neural network based grid side controller is adapted to provide low total harmonic distortion at the point of common coupling. The outcomes of the simulated and test models are introduced to approve the boosting capacity and performance of the proposed MTPACFC.
