"This textbooks demonstrates the application of software tools in solving a series of problems from the field of designing power system structures and systems. It contains four chapters : The first chapter leads the reader through all the phases necessary in the procedures of computer aided modeling and simulation. It guides through the complex problems presenting on the basis of eleven original examples. The second chapter presents application of software tools in power system calculations of power systems equipment design. Several design example calculations are carried out using engineering standards like MATLAB, EMTP/ATP, Excel & Access, AutoCAD and Simulink. The third chapters focuses on the graphical documentation using a collection of software tools (AutoCAD, EPLAN, SIMARIS SIVACON, SIMARIS DESIGN) which enable the complete automation of the development of graphical documentation of a power systems. In the fourth chapter, the application of software tools in the project management in power systems is discussed. Here, the emphasis is put on the standard software MS Excel and MS Project."

"Mengikuti tren global dari mengadopsi energi terbarukan ke dalam sistem tenaga listrik, banyak arus langsung (DC) rumah konsep yang diusulkan, karena sebagian besar energi terbarukan sumber tegangan DC. Penulisan ilmiah ini membahas pengembangan pengisian baterai yang ringan, rendah profil, dan terpasangn di dalam pada sepeda listrik yang tidak mengambil ruang yang berlebihan dan kompatibel untuk sistem DC rumah. Oleh karena itu, inverter yang umum digunakan dapat dihilangkan karena menghasilkan kerugian konversi daya yang lebih rendah. Desain topologi Half bridge resonant LLC dalam frekuensi switching tinggi di atas 1MHz menggunakan magnetis planar dilakukan untuk memilih Konverter DC-DC yang paling sesuai. Untuk mencapai efisiensi tinggi dalam frekuensi switching tinggi dan untuk mengurangi ukuran charger, perangkat divais elektronika wide band gap (wbg) yang digunakan. Langkah-langkah metodologi desain diusulkan dan divalidasi melalui simulasi pada rangkaian yang mengonversi 120 V dari input ke kisaran tegangan output 48-55 V di 0,5 kW

Following the global trend of adopting renewable energy into the electric power system, many direct current (DC) House concepts are proposed, because most of the renewable energy sources are DC voltage. This Scientific writing discusses the development of lightweight, low profile, and the built-in electric bike charger that does not take up excessive space and are compatible for home DC systems. Therefore, commonly used inverters can be eliminated as it generates lower power conversion losses. The topology design for the Half-bridge resonant LLC in high switching frequencies above 1MHz using planar was performed to select the most suitable DC-DC converter. To achieve high efficiency in high switching frequencies and to reduce the size of the charger, wide band gap (WBG) devices are used. Step-by-step in design methodology is proposed and validated through simulation on the circuit convert 120 V from input to output voltage range 48-55 V at 0.5  KW"
