摘要

本篇論文主要是將新型零電流切換脈波寬度調變之輔助電路，運用在單相單開關升壓式功率因數修正器，以完成主動開關在零電流狀態下切換與被動開關在零電壓狀態下切換，並且利用電路當中的電流路徑僅流過輔助開關電路的特性來降低導通損失。以平均電流模式作為功率因數修正之控制方法，使電感器電流工作在連續導通模式下，達成功因修正效果，除了詳述所提電路架構的七個狀態之分析，本論文尚推論零電流切換之共振條件以及共振元件設計等法則。
最後本論文以輸入交流80 V~270 V、輸出直流400 V、切換頻率30 kHz以及輸出功率500 W作為所提新型零電流切換之升壓型功率因數修正器規格，來驗證所提理論之正確性。

This thesis uses a new zero-current switching PWM (ZCS-PWM) auxiliary circuit in the presented ZCS-PWM boost power factor corrector to perform ZCS in the active switches and zero-voltage switching (ZVS) in the passive switches. Furthermore, soft commutation of main switch is achieved without additional current stress by the presented ZCS-PWM auxiliary circuit. A significant reduction in the conduction losses is achieved by circulating current for the soft switching flows only through the auxiliary circuit. According to the basic principle, the average current mode is used to control the presented ZCS-PWM boost power factor corrector in the continuous conduction mode (CCM). Seven transition states for depictry the behavior of the ZCS-PWM boost power factor corrector in one switching period are described.
The specification of the ZCS-PWM boost power factor corrector rated at 500 W, operating at 30 kHz, with an input alternating voltage of 80 ~ 220 Vrms and an output voltage 400 Vdc, has been implemented to verify the theoretical discussions.
