Pengendalian Tegangan Keluaran DC-DC Boost Converter Tipe Voltage Doubler Menggunakan Mikrokontroler STM32F1038CT

Abstract

Five-level inverter is widely used in many industrial applications, for example as a three-phase electric motor drive, PLTS, etc. This inverter works using two separated DC voltage sources in order to form different voltage level. Five-level inverter using one DC voltage source will be more efficient. A DC-DC boost converter on Voltage Doubler type is used in order to solve the problem. The focus of this research is on controlling the DC-DC boost converter on Voltage Doubler type. The switch control method uses a shifted pulse width modulation of 1800. To get a suitable output voltage, an output voltage control system is applied. A proportional and integral type control is implemented using STM32F1038CT microcontroller. The output voltage controlled DC-DC boost converter is validated through computational simulation with Power Simulator software and as the final step will be implemented on hardware in the laboratory. Based on the simulation and implementation, Voltage-Doubler type of DC-DC boost converter is able to produce the required output voltage, which is two times greater than the conventional DC-DC boost converter output voltage.

Perancangan Dan Identifikasi Kendali Pid Pada Aliran Hidrogen Sumber Ion Siklotron Decy 13

“…Selain menggunakan metode ZN ada beberapa kriteria dasar dalam mengolah error yang terjadi dalam suatu sistem antara lain integral of absolute error (IAE) dan integral of time multiplied by absolute error (ITAE). IAE merupakan integral dari nilai mutlak error tiap satuan waktu [14]. Metoda ini banyak dipakai untuk menghilangkan nilai osilasi yang terjadi pada sistem dan sangat efektif dalam menghilangkan error kecil.…”

Optimization of Off-Grid Solar Generating System With DC-DC Converter

“…While research entitled "Charging System Design Battery with Solar Panel Based DC-DC Converter," DC-DC converter can regulate PV voltage up to 25V [2]. Based on the study entitled "Design of a Hybrid PLT with a Two-Way Dc-Dc Converter at the Diponegoro University ICT Building Using Matlab Simulink Software", when the power generated by the solar panels is insufficient to supply the load, the program algorithm activates boost mode on the Bidirectional DC-DC Converter, causing it to discharge the battery, which transfers power from the battery to the load [3].…”

“…Therefore, if the energy is low, it will be increased. Likewise, if it is too high, it will be lowered by the DC-DC converter so that the resulting voltage becomes stable [3].…”
