ABSTRACTPower electronic circuits usage such as of inverters and switched-mode power supplies (SMPS), which have switching frequencies at high frequencies, have an impact on the appearance of disturbance at high frequencies. Development of power electronic circuit technology has also begun to be widely used in modern household appliances, as well as increasing research on household appliances and PV system that produce disturbances in range of 9-150 kHz, with this base, the author conducted research on the analysis of the characteristics of disturbances and behavior of the disturbances produced by household appliances in the frequency range of 9-150 kHz in on-grid PV system. Measurements were made in the EPES room of MRPQ building at Faculty of Engineering UI, using a sunny boy solar inverter which is an inverter type on the on-grid PV system. To confirm the power used in the equipment or load the Power Quality Analyzer is used, and for disturbances using a picoscope, measurement results are processed into a frequency domain to facilitate analysis. This study results indicate that household equipment generates disturbances, and variations in power usage and equipment combinations in the same system also affect the value of the disturbances and frequency changes in the disturbances."

"This book provides a concise introduction to the physical foundations of the electro-discharge technology and applies it to the drilling of wells, the demolition of reinforced concrete objects, and the cutting of cracks in rocks and concrete. The electro-physical basis of this technology and the technical implementation of using spark discharge as a working tool in the above-mentioned contexts are also briefly considered. "

"Pada saat ini pengembangan dan penggunaan kendaraan listrik masif dilakukan. Kendaraan listrik membutuhkan konverter DC-DC untuk menurunkan tegangan tinggi dari sumber utama — baterai besar — ke tegangan rendah (step down DC-DC converter) sehingga tegangan dapat digunakan oleh komponen - komponen yang membutuhkan tenganan rendah. Topologi konverter DC-DC yang umum digunakan adalah konverter dengan switch tunggal seperti flyback converter dan switch ganda seperti half bridge converter. Akan tetapi kedua topologi tersebut memiliki nilai voltage and current stress (spike, overshoot, dan ringing) yang tinggi dengan demikian akan menimbulkan rugi - rugi daya yang besar serta membutuhkan komponen dengan rating tegangan dan arus yang tinggi. Phase Shift Full Bridge DC-DC Converter (selanjutnya akan disebut PSFB) merupakan salah satu topologi konverter DC-DC terisolasi yang memiliki konfigurasi empat switch (full bridge / active bridge) sehingga dapat memiliki voltage and current stress yang lebih rendah dibandingkan dengan kedua topologi sebelumnya, dengan demikian dapat dihasilkan rugi - rugi daya yang lebih rendah [1]. Tegangan output PSFB ditentukan dari pergeseran fasa active bridge yang dihasilkan melalui kolaborasi keempat switch MOSFET oleh gate driver [2]. Gate driver dikendalikan oleh mikrokontroler yang sudah diporgram dengan algoritma pergeseran fasa dan juga closed loop control. Dalam karya ilmiah ini berhasil dibuat purwarupa PSFB yang dapat menghasilkan tegangan output dinamis sesuai dengan pergeseran fasa dalam active bridge. Nilai tegangan output memiliki kecenderungan meningkat dalam rentang pergeseran fasa 0º sampai 180º dan memiliki kecenderungan menurun dalam rentang pergeseran fasa 180º sampai 360º. Diperoleh juga hasil yang menunjukkan bahwa purwarupa PSFB sudah terintegrasi dengan closed loop control sehingga sistem dapat menghasilkan tegangan output sesuai dengan setpoint yang ada dalam program. Sistem dapat mempertahankan tegangan output sesuai setpoint meskipun diberikan variasi tegangan input dan variasi beban.

Currently, the development and widespread use of electric vehicles are underway. Electric vehicles require a DC-DC converter to convert the high voltage from the main source — a large battery — to a lower voltage (step-down DC-DC converter), allowing it to be used by components that require low voltage. Commonly used topologies for DC-DC converters include single-switch converters like the flyback converter and dual-switch converters like the half-bridge converter. However, both topologies have high voltage and current stress values (spikes, overshoot, and ringing), resulting in significant power losses and the need for components with high voltage and current ratings. The Phase Shift Full Bridge DC-DC Converter (hereafter referred to as PSFB) is one of the isolated DC-DC converter topologies with a four-switch configuration (full bridge/active bridge). This configuration allows it to have lower voltage and current stress compared to the previous two topologies, thereby resulting in lower power losses [1]. The output voltage of the PSFB is determined by the phase shift of the active bridge generated through the collaboration of the four MOSFET switches controlled by a gate driver [2]. The gate driver is controlled by a microcontroller programmed with a phase shift algorithm and closed-loop control. In this scientific work, a prototype of the PSFB has been successfully developed, capable of producing dynamic output voltage in accordance with the phase shift in the active bridge. The output voltage tends to increase in the phase shift range of 0º to 180º and decrease in the range of 180º to 360º. Furthermore, results indicate that the PSFB system has been integrated with closed-loop control, enabling it to generate output voltage according to the various setpoint in the program. The system is able to maintain the output voltage according to setpoint, regardless of various of input voltages and loads."

"Pada zaman sekarang, kebutuhan daya listrik semakin meningkat seiring dengan pertumbuhan penduduk dan mengakibatkan pertumbuhan beban. Dalam penyediaan daya listrik ke konsumen harus memenuhi standar kualitas daya listrik sesuai dengan tingkat mutu pelayanan yang telah ditentukan. Salah satu permasalahan pada kualitas daya adalah harmonisa yang merupakan permasalahan yang berkaitan dengan penyimpangan arus, tegangan, dan frekuensi pada besaran listrik. Harmonisa merupakan gangguan yang sering terjadi dalam kualitas daya listrik. Penelitian ini membahas tentang berapa besar tingkat harmonisa arus dan tegangan yang terjadi pada suatu bangunan perkantoran, yang kemudian dibandingkan dengan standar yang berlaku, apakah masih dalam batas toleransi atau tidak untuk sistem. Apabila tingkat harmonisa arus dan tegangan melebihi batas standar, maka dirancang suatu filter pasif dengan tipe single tuned filter yang digunakan untuk dapat mereduksi besarnya harmonisa arus dan tegangan yang terjadi pada objek bangunan yang diteliti. Berdasarkan hasil pengukuran dapat diketahui bahwa besarnya arus harmonisa total (THD) yang terjadi adalah sebesar 17% dengan arus harmonisa orde 3,5, dan 7 berturut-turut sebesar 80A, 350A, 160A. tingkat arus harmonisa total melenihi standar yang direkomendasikan sehingga dirancang filter single tuned agar dapat mereduksi harmonisa yang terjadi.

Now, power electricity is more increasing along with growth of population and growth of electricity load. Power electricity supply to consumer must have power quality standart in accordance with standart of quality service. One of problems in power quality is harmonics, which is problems with deviation of current, voltage, and frequency in electric quantity. Harmonics is one of problems that usually happen in electric power quality. This research will explain about how big level of harmonics current and voltage in building office. Then compare with standart in textbook law, which is still can be tolerance with limit or not in the system. If level of harmonics current and harmonics voltage surpass with the limit standart, then must be design with filter passive type single tuned filter to reduction harmonics current and voltage in object of building office. Based on measurement, resultant of total harmonics current (THD) is 17 % and harmonics current orde 3, 5, 7 is 80A, 350A, 160A. the level of total harmonics current is surpass with the recommendation standart. So, must have design single tuned filter to reduction harmonics."
