“…Additional boosting circuits and a dual switch-based flipping capacitor are employed to raise the gain. The topologies developed in [16] can attain high voltage gain (HVG) with higher efficiency. Nevertheless, the incorporation of a PV source deteriorates the input current smoothness and lessens the output voltage level.…”

DC-DC converters with significant gain, ripple-free input current, and shared ground are required to elevate the output voltages of batteries, fuel cells, and Photovoltaic sources. The proposed topology utilizes a solitary switch to control the circuit and it has additional inculpation of a voltage doubler cell at the load side, a switch capacitor cell in the middle, and a quadratic cell at the output side. These cascaded configurations lead to significant voltage gains at moderate duty cycle rates. Additionally, the voltage stress over the power components is negligible, coming in under one-third of the resultant voltage. Moreover, the number of cells at the input and output side can be extended to obtain high voltage according to the requirements of the load. The gain in voltage, efficiency, and normalized voltage stress of the semiconductor elements in the circuit are examined concerning other solutions found in the literature. Eventually, photovoltaic and battery sources were included to analyze the proposed topology to confirm the circuit’s multifaceted functionality. The circuit was developed for 270 W, 440 V output from 36 V input, and a 40 kHz switching pulse was used to drive the switch. The theoretical and simulation analysis states that incorporating photovoltaic and other sources did not deteriorate the transformation efficiency. Simulink and PSIM analysis found that the circuit successfully transferred power from source to load. ABSTRAK: Penukar DC-DC yang mempunyai gandaan ketara, input arus bebas riak dan pembumi berkongsi penting bagi meningkatkan voltan keluar bateri, sel bahan api dan sumber fotovolta. Topologi yang dicadangkan ini menggunakan suis tersendiri bagi mengawal litar dan ia mengandungi sel pendua voltan tambahan bagi menghentikan arus di bahagian beban, sel suis kapasitor di tengah dan sel kuadratik di bahagian voltan keluar. Konfigurasi berturutan ini membawa kepada gandaan voltan ketara pada kadar kitar tugas sederhana. Tambahan, tekanan voltan ke atas komponen kuasa boleh diabaikan, iaitu satu pertiga daripada voltan terhasil. Selain itu, bilangan sel di bahagian kemasukan dan keluaran arus boleh dilanjutkan bagi mendapatkan voltan tinggi mengikut keperluan beban. Gandaan voltan, kecekapan dan tekanan voltan ternormal pada bahan dalam litar semikonduktor diperiksa dengan menyamai penyelesaian lain yang ditemui dalam kajian terdahulu. Akhirnya, sumber fotovolta dan bateri dimasukkan bagi menganalisis topologi yang dicadangkan bagi mengesahkan fungsi pelbagai rupa litar. Litar yang dibangunkan ini digunakan pada kuasa 270 W, pada aras voltan 440 V dengan kemasukan voltan 36 V dan suis operasi berfrekuensi 40 kHz. Analisis teori dan simulasi menyatakan bahawa gabungan fotovolta dan sumber lain tidak mengurangkan kecekapan transformasi. Analisis Simulink dan PSIM mendapati litar ini berjaya memindahkan 95% kuasa dari sumber kepada beban.

This study proposes a cutting‐edge AC/DC converter designed for medium‐power PFC applications. The converter is a single‐phase, single‐stage boost‐push–pull model. It consists of three key components: an interleaved boost, a push–pull, and a resonant tank circuit. The interleaved boost operates in DCM mode and serves as power factor correction. The push–pull converter includes a resonant tank on the secondary side of the transformer to achieve ZVS. The two switches control the boost and the push–pull circuits to create a single‐stage converter. The converter in question provides an array of advantages, such as zero voltage switching (ZVS), an intermediate bus voltage that is independent of the load, and a low‐ripple input current, all of which can be achieved without the need for additional filtering. The present article provides a comprehensive overview of the design procedure, simulation and experimental results, and separate operating modes analysis. To verify the design and simulation results, a 200‐W interleaved boost push–pull converter (IBPPC) prototype is implemented. Finally, because it is crucial to maintain the voltage of the bus capacitor within an acceptable range, this study investigated the impact of load variation on the bus voltage.
