The Relationship

This paper presents a comparative study of the application of Thyristor versus IGBT in AC-DC controlled power converter. Both simulation and practical experiment have been carried out to test the relationship between the average output voltage (Vdc) with firing angle (α, for Thyristor) and triggering pulse width (, for IGBT). Also the total harmonic distortion (THD) has been observed in both the cases. It is observed that IGBT based power converter introduces more harmonics in the system, in spite of more symmetrical output voltage wave shape.

Converter Design

Abstrak— Paper ini menampilkan desain double boost converter yang mempunyai kemampuan menggandakan tegangan dua kali lipat berturut  turut beban DC yang menghasilkan tegangan output tambahan atau cadangan suplai pada beban. Pada umumnya double boost converter ini adalah konverter daya DC to Dc meningkatkan tegangan dari input (pasokan) ke output (beban) di desain menunjukkan bahwa dengan inputan sumber AC yang di searahkan terlebih dulu dengan converter penyearah berfungsi untuk mengatur kecepatan motor BLDC. Untuk pengontrolan pada beban motor menggunakan PI controller ( Proportional Integrator) dimana  parameter PI controller diperoleh dari trial eror. PI controller juga berfungsi memperbaiki gelombang keluaran dan kecepatan motor BLDC. Kata kunci : Motor BLDC, Double Boost Converter, PI controller. Abstract— This paper features a double boost converter design that has the ability to double the successive voltage in a DC load which results in an additional output voltage or supply reserve at load. In general, this double boost converter is a DC to Dc power converter increasing the voltage from input (supply) to output (load) in the design shows that the input AC source is aligned first with the rectifier converter to regulate the speed of the BLDC motor. To control the motor load using a PI controller (Proportional Integrator) where the PI controller parameter is obtained from the trial error. The PI controller also functions to improve the wave output and speed of the BLDC motor.
