摘要

傳統的二極體整流的結構在輸入端會產生嚴重的電流失真，對電
網造成有害的諧波電流。因為IEC1000-3-2 對於輸入電流<16A 及
IEC1000-3-12 輸入電流>16A 的設備有規範對電網產生的諧波電流總量。因
此使用二極體整流的方式已經開始被具有低諧波電流、高功率因數的轉換
器所取代。
本技術報告主要目的係研究單週期控制之功率因數修正電路，此控制
方式可以應用在電腦及工業領域。單週期控制是一種非線性的控制技術，
控制器的結構非常簡單，它包含積分器、數個正反器以及比較器等組合而
成。電路架構採用升壓型式的轉換器，並使用 SIMPLIS 模擬軟體及使用簡
化的模型來進行電路仿真。
依據仿真的結果，使用類比控制器制作一台三相功率因數的轉換器，
其輸出功率為9kW / 800V 直流電輸出的雛型機。其控制核心採用國際整流
(IR) 公司IR1150 控制晶片，整機是由三個單相輸入的功率因數轉換器組
合而成。使用實驗的方法驗證及測試，其結果證明了理論分析的有效性、
可行性及一些設計的考量。

The rectification mechanism of the conventional diode produces a severe
current distortion to the input port which results in an unwanted injection
harmonics into the power grid. However, there are some limits on the amount
of harmonic injection for all equipment to the power grid. For example, the
standard of the International Electro-technical Commission IEC 61000-3-2
confines the input current has to be less than 16A , whereas the standard IEC
1000-3-12 restricts the input current has to be greater than 16A. The diode
rectifier has been replaced by the power quality converter which has low
harmonics with high power factor performance.
In this technical report, we apply the one cycle control (OCC) strategy into the
circuit of the active power factor correction (PFC). The OCC scheme is a
nonlinear control technology which has been used in many industrial
applications. This controller has a simple structure which consists of
integrators, flip-flops, comparators and so on. The topology of the power factor
correction has used the boost type, whereas simulations are utilized the software
SIMPLIS.
Base on simulation results, an analog controlled prototype for the three-phase
III
boost PFC has been developed and tested in a power of 9kW and a DC bus
voltage of 800V, whose control IC is the IR1150 device and power stage consists
of three single-phase PFC converters. Furthermore, experiments are executed
as well. Satisfactory results are obtained to confirm the effectiveness and the
feasibility of our theoretical analyses and design considerations.
