Riset ini merupakan riset lanjutan dari riset sebelumnya. Pada riset sebelumnya telah mengusulkan pengujian pada 6 rangkaian dc-dc boost converter dengan konfigurasi berbeda sehingga dihasilkan 3 rangkaian dc-dc boost converter dengan hasil terbaik. Pengendalian lebar pulsa PWM digunakan untuk mengetahui kemampuan awal rangkaian dalam menghasilkan penguatan tegangan. Kendali PI Static dan PI Adaptive juga ikut diuji untuk mengetahui kemapuan rangkaian saat terjadi peralihan tegangan masukan. Pengujian berbasis simulasi menggunakan pemrograman SPICE. Pengujian tegangan linear dan nonlinear dilakukan untuk mengetahui hasil kendali PI terbaik. Hasil yang diperoleh dari ketiga jenis rangkaian mampu menghasilkan penguatan keluaran diatas 200V. Hasil akhir pengujian diperolah rangkaian BCI dengan pengendalian PI Adaptive mampu menghasilkan tegangan keluaran sebesar 249.069 V dengan beban 300Ω, sedangkan untuk beban 500Ω, menghasilkan tegangan keluaran sebesar 249.679 V dan 250.244 V untuk beban 1KΩ. Diakhir Pengujian tegangan nonlinear dilakukan diakhir pengujian untuk mengetahui kemampuan dari pengendalian PI Adaptive yang diusulkan. Pengendalian PI Adaptive mampu mempertahankan nilai tegangan keluaran saat terjadi peralihan tegangan masukan.This research is a continuation of previous research. Previous research has proposed testing 6 dc-dc boost converter circuits with different configurations so that 3 dc-dc boost converter circuits are produced with the best results. PWM pulse width control is used to determine the initial ability of the circuit to generate voltage gain. Static PI and Adaptive PI controls were also tested to determine the ability of the circuit when there is a change in input voltage. Simulation-based testing using SPICE programming. Linear and nonlinear stress tests were carried out to determine the best PI control results. The results obtained from the three types of circuits can produce output gain above 200V. The final result of the test is that the BCI circuit with Adaptive PI control is able to produce an output voltage of 249,069 V with a load of 300Ω, while for a 500Ω load, it produces an output voltage of 249,679 V and 250,244 V for a 1KΩ load. At the end of the test nonlinear stress is carried out at the end of the test to determine the ability of the proposed Adaptive PI control. Adaptive PI control can maintain the value of the output voltage when there is a change in the input voltage.

This paper presents the design model and simulation of a double-stage single-phase grid-connected PV system. This system includes an MPPT DC-DC boost power converter and a transformer-less single-phase DC-AC power inverter, which is connected to the power grid with an LCL filter. In the DC-DC boost converter, the Perturb and Observe algorithms are combined. The output voltage of the DC-DC converter is regulated, and the DC/AC output voltage is synchronized with the grid. The MATLAB-Simulink environment is used for the closed-loop simulation of the proposed setup. The simulation results are presented for various solar irradiance conditions and show that photovoltaic current is generated and matches the phase of grid voltage.

“…To increase the voltage gain, a different family of converters has been reported on in [ 32 , 33 , 34 , 35 , 36 , 37 ], which combines a boost or buck–boost type of topology with diode and capacitor-based voltage multiplier rectifiers (DCVMR). Even though the DCVMR stage provides additional voltage gain, its ideal gain increases linearly with the number of levels (equivalent to the number of diodes).…”

Soft robots have the potential to fundamentally change interactions between robots and the surrounding environment, and between robots and animals, and robots and humans in ways that today’s hard robots are incapable of doing. However, to realize this potential, soft robot actuators require extremely high voltage supplies of more than 4 kV. The electronics that can satisfy this need currently are either too large and bulky or unable to achieve the high power efficiency required for mobile systems. To meet this challenge, this paper conceptualizes, analyzes, designs, and validates a hardware prototype of an ultra-high gain (UHG) converter that can support extremely large conversion ratios up to ∼1000X to provide up to 5 kV output voltage from an input voltage of ∼5–10 V. This converter is demonstrated to be able to drive HASEL (Hydraulically Amplified Self-Healing Electrostatic) actuators, a promising candidate to realize future soft mobile robotic fishes, from an input voltage range of a 1-cell battery pack. The circuit topology employs a unique hybrid combination of a high-gain switched magnetic element (HGSME) and a diode and capacitor-based voltage multiplier rectifier (DCVMR) to enable compact magnetic elements, efficient soft-charging in all flying capacitors, and adjustable output voltage capability with simple duty-cycle modulation. Achieving an efficiency of 78.2% at 15 W output power, while providing 3.85 kV output from 8.5 V input, the proposed UGH converter proves to be a promising candidate for future untethered soft robots.
