Rancang Bangun DC Power Supply Dari Sumber 1 Phasa Untuk Perbaikan Power Faktor dan Menurunkan THD Menggunakan Fullwave Rectifier Dengan Metode Switching PID-Fuzzy Pada Boost Konverter

摘要

Commonly AC to DC converter is non linier load because current switch process for obtain good output voltage. It poor condition with input side quality when current form is not sine again because appear low frequency harmonics and make the power factor is low. So in this final project describe about design of design of DC Power Supply From single Phase Source For Fixed Power Factor and Decrese THD With Fullbridge Rectifier And Switching PID-Fuzzy Method on Boost Converter where the current form is sine following the voltage input form and one phase with the voltage form. But after use boost converter then rise high frequency harmonics at input current, so filter EMI can reduced. Method of power factor correction and minimize THD value on this AC to DC converter is use boost pfc preregulator with conducted continue mode which helped with fuzzy PID controller to control switching of boost converter. This circuit such as rectifier AC to DC single phase, boost converter circuit, filter DC output, EMI filter, fuzzy PID controller and driver MOSFET . When this metode tested and the result obtain percent THD is 41% dan power factor value is 0.9 Key Words : AC to DC converter single phase, boost converter, boost pfc CCM, PID-fuzzy controller, EMI filter, power factor, total harmonics distortion
