dc.description.abstract | 本篇論文提出具有飛馳電容控制迴路和自適化固定導通時間控制之雙向三階轉換器,此轉換器能提供高效率因此適合應用於電池充電系統。在三階轉換器中飛馳電容的平衡與否尤其重要,本文提出了相較於其他平衡方式更簡單且有效的單點感測式平衡技術,僅由取樣保值電路以及運算轉導放大器組成的兩組電路即可實現,除了可以確保飛馳電容的平衡,還能減小電感電流漣波。除此之外,所提出的自適化固定導通時間控制的設計解決在固定導通時間控制下切換頻率變化大的問題,相較於傳統使用自適化固定導通時間控制的升壓轉換器,本文所提出的切換頻率變化小於6%,遠小於傳統控制下的13%。再者,所提出的雙向三階轉換器除了外迴路補償無法共用外,其餘兩個方向的電路(降壓模式或升壓模式)皆能共享控制元件,因此可以最小化控制電路的面積。此雙向三階轉換器晶片是由台積電0.18μm BCD製程所實現,轉換器的切換頻率設計在1.5MHz,由於三階轉換器本身的特性,功率開關的耐壓可以選擇為高壓側的一半。量測結果可以驗證本文所提出的功能在升壓及降壓模式皆可實現,並且沒有飛馳電容電壓失去控制和不匹配的問題,所提出的三階降壓轉換器在高轉壓比且負載為1A時效率可達95.89%,而所提出的三階降壓轉換器在負載為0.5A時效率可高達96.02%。 | zh_TW |
dc.description.abstract | This thesis presents a novel bidirectional three-level (TL) converter control scheme with a flying capacitor control loop and adaptive constant on-time (ACOT) control. The proposed bidirectional TL converter with high efficiency is beneficial for the battery charger system. Due to the flying capacitor balance issue in TL converters, the flying capacitor control with single-point sensing (SPS) formed by only two pairs of sample and holds (S/Hs) and operational transconductance amplifiers (OTAs) is proposed to balance the flying capacitor with a simpler design. The proposed SPS also minimizes the inductor current ripple. Besides, the proposed ACOT design solves the switching frequency variation issue, and the variation is less than 6%, which is much smaller than 13% in conventional boost converters with ACOT control. Additionally, both directions (buck mode or boost mode) share the same control elements except for the compensator. Consequently, the controller die area can be minimized. The proposed scheme is realized with a 1.5MHz switching frequency bidirectional TL converter IC in the TSMC 0.18 μm Bipolar-CMOS-DMOS process. Due to the characteristics of the TL converter, the stress of the switch is chosen with half of the high-side voltage. The measured result verifies that the functions are feasible in both directions, and there are no flying capacitor voltage runaway and mismatch issues. The proposed TL buck converter achieves an efficiency of about 95.89% at load 1 A in a high conversion ratio. For the proposed TL boost converter, the efficiency is up to 96.02% at load 0.5 A. | en |
