Implementasi DC-DC Boost Converter Menggunakan Arduino Berbasis Simulink Matlab

open access: yesJurnal Teknik Elektro Indonesia, 2020
Direct current (dc) voltage sources are one of the voltage sources most widely used for various purposes. Dc voltage can be obtained from a dc generator or by converting an ac voltage into a dc voltage using a power converter.

GridConnected CapacitorTapped MultiModule Voltage Source Converter

open access: yesQatar Foundation Annual Research Conference Proceedings Volume 2018 Issue 1, 2018
In this work, a new dc-ac converter is proposed for grid integration purposes, namely, capacitor-tapped multi-module dc-ac voltage source converter. The main advantages of the proposed converter when compared with the conventional dc-ac modular multilevel converter (assuming the same voltage rating of semiconductor devices) are: (i) employment of a ...

Isomorphic Relationships Between Voltage-Source and Current-Source Converters [PDF]

open access: yesIEEE Transactions on Power Electronics, 2019
Graph isomorphism phenomenon has been identified since the 1930s, which was first addressed in the graph-theoretical field and was thoroughly studied as a critical topic of computer science. In many research disciplines, isomorphism theory and dual principles are identified as powerful tools in the study of related subjects.
