AVERAGE CURRENT-MODE CONTROL OF DC-DC POWER CONVERTERSAn authoritative one-stop guide to the analysis, design, development, and control of a variety of power converter systemsAverage Current-Mode Control of DC-DC Power Converters provides comprehensive and up-to-date information about average cur

rent-mode control (ACMC) of pulse-width modulated (PWM) dc-dc converters. This invaluable one-stop resource covers both fundamental and state-of-the-art techniques in average current-mode control of power electronic converters featuring novel small-signal models of non-isolated and isolated converte

r topologies with joint and disjoint switching elements and coverage of frequency and time domain analysis of controlled circuits. The authors employ a systematic theoretical framework supported by step-by-step derivations, design procedures for measuring transfer functions, challenging end-of-chapt

er problems, easy-to-follow diagrams and illustrations, numerous examples for different power supply specifications, and practical tips for developing power-stage small-signal models using circuit-averaging techniques. The text addresses all essential aspects of modeling, design, analysis, and simul

ation of average current-mode control of power converter topologies, such as buck, boost, buck-boost, and flyback converters in operating continuous-conduction mode (CCM). Bridging the gap between fundamental modeling methods and their application in a variety of switched-mode power supplies, this b

無橋式功因修正轉換器研製

為了解決DC-DC converter的問題，作者黃禎岳 這樣論述：

本論文目的在研製一無橋式功因修正轉換器，硬體電路以圖騰柱型功率因數修正電路為核心，利用外迴路電壓感測電路與內迴路電流感測電路完成本控制。本研究採用平均電流控制法來實現功率因數修正功能。平均電流控制法以雙迴圈PI控制器來實現，由輸入電壓極性與波形角度傳給雙迴圈PI控制系統運算，外迴圈PI控制器控制電壓，內迴圈PI控制器控制電流，軟體是以瑞薩電子公司生產的R5F562TAADFP數位訊號處理器實現，經實測結果顯示功率因數可達0.98以上，總諧波失真率最大為11.644%。證明本控制器可達功率因數修正的效果。

基於網路化監控系統於發光二極體之功率控制及其數據化分析的時間序列設計模式

為了解決DC-DC converter的問題，作者蒲里亞 這樣論述：

發光二極體(LEDs)的技術品是有節能效益、照度優、效能優、長壽命優，而被認為是許多光源應用中最佳來源之照明。然而影響LEDs的最大問題所在就是其壽命週期，包括LEDs的光效能下降或突然失效，而不穩定的正向電壓、不足的限制電流和高溫會導致LEDs光衰退的發生。所以能夠即時監控LEDs參數物理變化，以及在特定條件之下控制LEDs的功率及是減少光衰退的方法之一。本論文研究是基於應用Web的網路便利性方式來構建時間序列之參數監控化系統和一個LEDs電源控制系統，以樹莓派(Raspberry Pi)和ESP32作為系統的主要設備。為了讓系統介面給使用者方便來應用，建構兩個用戶界面(UI)，以及參數數

據存取方式和方便管理時間序列之資料庫數據，作為測量物理變化和執行動作由ESP32和ESP8266處理，並將傳輸和執行設備鏈結到系統，而蒐集數據與存取並藉由無線網路鏈結傳遞到Raspberry Pi，以完成更好的移動性與遠程使用MQTT發布/訂閱消息連接協議。因有Web的網路應用程序於即時監測和控制，任何設備可透過Web網路瀏覽器查詢。監控UI使用TIG (Telegraf, InfluxDB, and Grafana)堆疊技術，這是一個平臺的字體縮寫，對時間序列之參數與資料庫數據進行擷取、儲存、繪圖和警示。另外對電源控制UI是基於Web網路之應用方式來做使用HTML語言與Javascript構
