Abstract

Inverter merupakan salah satu elemen terpenting dalam pemanfaatan energi terbarukan. Dengan menggunakan teknik pensaklaran tertentu, inverter dapat mengkonversi tegangan DC menjadi tegangan AC dengan metode penyaklaran tertentu. Pada tugas akhir ini metode penyaklaran yang dipilih adalah Sinusoidal Pulse Width Modulation (SPWM) merupakan metode pembangkit gelombang sinusoida. Data pola-pola amplitudo gelombang sinusoida dalam satu siklus dihasilkan menggunakan perhitungan matematis. Hasil penelitian menunjukan metode unipolar SPWM mudah diimplementasikan dalam mikrokontroler 32-bit. Sinyal carrier dirancang sebesar 10 kHz dan variasi frekuensi input pada nilai 50 Hz, 100 Hz, 150 Hz, 200 Hz dan 250 Hz. Hasilnya adalah bentuk tegangan keluaran inverter berupa gelombang sinusoida. Error terbesar yang didapat dari kelima variasi input ada pada frekuensi 200 Hz sebesar 2,09 Hz.

Inverter is one of the most important elements of utilization of renewable energy. By using a specific switching technique, the inverter can convert DC voltage into AC voltage with certain removal methods. In this final task the method of sealing is selected is Sinusoidal Pulse Width Modulation (SPWM) is a method of Sinusoide wave generation. Data amplitudes of Sinusoida wave patterns in a single cycle is generated using mathematical calculations. The results showed that unipolar SPWM methods are easily implemented in 32-bit microcontrollers. The carrier signal is designed at 10 kHz and the input frequency variation at the value of 50 Hz, 100 Hz, 150 Hz, 200 Hz and 250 Hz. The result is the output voltage form of inverter wave Sinusoida. The biggest Error gained from the five input variations is at a frequency of 200 Hz at 2.09 Hz.
