ABSTRAKDewasa ini teknologi energi terbarukan biasanya menggunakan mesin listrik sinkron Alternating Current (AC) pada pembangkit listrik tenaga angin. Generator listrik sinkron AC menggunakan brush pada proses eksitasi yang membutuhkan perawatan berkala sehingga rumit jika diaplikasikan pada Pembangkit Listrik Tenaga Angin. Pada penelitian ini generator akan menggunakan mesin Switched Reluctance yang dioperasikan sebagai Switched Reluctance Generator (SRG). Untuk menghasilkan keluaran arus yang optimal, SRG akan dioperasikan dengan mengatur sudut penyalaan fasa menggunakan metode single pulse. Metode pensakelaran ini diatur oleh input capture fasilitas mikrokontrol dsPIC 30F4012. Penelitian ini telah diverifikasi dengan simulasi Simulink MATLAB dan pengujian alat. Hasil pengujian optimal dibuktikan pada sudut penyalaan θon = 40 derajat dan θoff = 170 derajat menghasilkan arus discharging sebesar 7.6 A dengan kecepatan 1647.1 RPM ditandai dengan bentuk gelombang arus yang ideal. Hasil arus discharging yang optimal dapat meningkatkan kinerja SRG, sehingga metode ini dapat diaplikasikan pada pembangkit listrik tenaga angin.Kata kunci: SRG, dsPIC30F4012, sudut penyalaan, single pulse ABSTRACTNowadays, renewable energy technology usually uses AC synchronous electric machines in wind power. AC synchronous generator uses a brush in the excitation process, which requires periodic maintenance so it is complicated if applied to wind power. In this research, the generator will use a Switched Reluctance machine that operated as a SRG. To produce an optimal current, the SRG will be operated by adjusting the ignition angle using the single pulse method. This method is controlled by input capture of the microcontroller dsPIC 30F4012. This research has been verified by simulating Simulink MATLAB and testing device. The optimal test results are proven at the ignition angle θon = 40 degree and θoff = 170 degree produces a discharging current of 7.6 A with a speed of 1647.1 RPM characterized by the ideal current waveform. The optimal discharging current results can improve the performance of the SRG, so this method can be applied to wind power.Keywords: SRG, dsPIC30F4012, the ignition angle, single pulse

Background: Advancements in Power Electronics made a huge breakthrough in the industrial sector majorly in the development of Switched Reluctance Machines (SRM). The main objective of this paper is to develop a two Phase H-bridge converter for 250W SRM and compare its advantages and disadvantages over the other converters. Methods: A time based simulation has been carried out to evaluate the performance of the converter at various loads. Different parameters of the machine and converter are studied and the results are verified experimentally. Results: The obtained test results of the converter performance are found to be in good agreement with the simulation and the efficiency of the converter is compared with the existing R-Dump topology. Conclusion: It is concluded that the proposed H-Bridge converter for a two phase SRM is better than the R-Dump converter in terms of efficiency and reduced size.
