單位功率因數之交流直流轉換器的分析與設計

Abstract

The main subject to investigate here is designing a controller make the output voltage follow with the voltage command as soon as possible when loading is variating in AC-DC rectifier with high power factor. To improve the time response by designing a voltage controller, the active full bridge rectifier is adopted. A approximation mathematics model is established by the way of averaging and linearization, and then the adaptive PI Controller and Linear Quadratic Regulator are designed to make the output voltage follow with the voltage command rapidly and stably.
