數位控制升壓式功因修正器之研製
Implementation of a Boost Power Factor Corrector with Digital Control
摘要
本論文主要目的是以數位訊號處理器實現高功率因數修正器之研究。本文電路採用六開關模組架構，可實現升壓和降壓式功因修正器，而功率因數修正方法則採用平均電流控制，利用內迴路控制電流，使轉換器具有高功因特性；並利用外迴路控制電壓，使輸出電壓穩壓，而不受線電壓及負載電阻變動影響。 本論文首先進行內、外迴路的小訊號分析，推導需要的誤差補償器，再利用Matlab / Simulink建立系統模型，驗證設計之控制器可行性，最後以六開關模組架構電路與數位訊號處理器作為控制平台，藉以實現平均電流控制，而取代類比元件，以達到數位化、體積小、設計彈性大等目的。經由實測結果，設計之功率因數修正器可將功率因數由0.3提升至0.7左右。

The purpose of this thesis is to achieve a high power factor corrector. The circuit uses six switches module, it can realize boost and buck power factor corrector, and the control method is average current control, it uses inner return route to control the current to achieve high power factor converter; also uses outer return route to control the voltage to achieve the output voltage stable without effected by the change of line voltage and load resistance. This thesis analyze the small signal analysis of the inner and outer return route first, inferential reasoning the needed error compensators. Then uses Matlab/ Simulink to build the system model to test the feasibility of designed controllers. Last uses the digital signal processor to control the circuit built by the six switches module to achieve average current control. It would replace the analog elements to achieve the purpose of small volume and high design elasticity. By the experiment, the power factor corrector only raises the power factor from 0.3 to 0.7.
