Novel zero-voltage switching techniques for pulse-width-modulated converters

open access: yes, 2009
Two new classes of soft switching pulse-width-modulated (PWM) converters, named zero-voltage-switched (ZVS) PWM converters and zero-voltage-transition (ZVT) PWM converters, are proposed. The proposed ZVS-PWM converters combine the merits of conventional

Lowest-Voltage-Switching and Zero-Voltage-Switching Control for Buck Converter

open access: yes, 2010
本論文主要針對降壓轉換器,提出操作於連續/非連續之臨界模式的低電壓切換與零電壓切換之積體化電路控制技術。此技術可自動補償電路延遲,並在低汲源電壓/零汲源電壓的狀態時,將功率電晶體導通,不需任何複雜計算時間的電路,也不需任何外部輔助元件。本論文提出之控制電路,也可應用於其他電源轉換器上,如昇壓、昇-降壓、及返馳式轉換器。本論文內容包含控制分析、電路組成、及輸入電壓5V、輸出電壓各為1.8V、3.3V的實驗結果;實驗結果顯示具低電壓切換/零電壓切換技術之降壓轉換器,比傳統降壓轉換器具更高的轉換效率 ...
