Rancang Bangun DC Power Supply Dari Sumber 3 Phasa Untuk Perbaikan Power Faktor dan Menurunkan THD Menggunakan Fullwave Rectifier Dengan Metode Switching PID-Fuzzy Pada Boost Konverter

Three phase fullwave rectifier is one of changes technique from 3 phase Ac voltage to Dc voltage. Rectification process by diode, caused phase shifting of current to voltage and also affected in occuring harmonic in input side, so power factor is generated arround 0.6 and Thdi 17.5 %. With boost converter circuit which it switching use PID Fuzzy method,the input power factor is arround 0.86 and THDi 41.47% for 100W lamp, and also with 200W lamp the power factor is arround 0.86 with THDi 50.03%. To reduce THDi quantity,EMI filter circuit is used in input side so the final result of THDi is arround 24.15% with 0.89 power factor for 100W lamp. For 200W lamp THDi is arround 26,15% with 0,89 power factor. Keyword : 3 Phase fullwave rectifier, THDi, Power Factor, Boost Converter, EMI Filte
