During the circuit design, the author analyzed the basic principle of the direct current motor, pwm control, h - bridge power driver, and two control techniques of h - bridge power drive circuit, designed its general structure, so the feasibility of the design is confirmed. then, reference, oscillator, power dmos gate drive circuit ( charge pump, bootstrap ), and dead time generation circuit are designed and analyzed in the sub - circuits. a current - controlled oscillator is presented in this thesis
在電路設計中,作者介紹了直流電機的工作原理和數學模型、脈寬調制( pwm )控制原理、 h橋電路基本原理和h橋功率驅動電路的兩種控制模式,設計了驅動電路的總體結構,給出了電路的功能模塊,確定了設計的可行性,然後在子電路模塊中,重點分析設計了基準源電路、振蕩器電路、高端功率管柵驅動電路(電荷泵及自舉電路) 、低端功率管柵驅動電路和死區時間產生電路。Section iii proposes a possible organization of a reactive power market, a regional reactive power market established according to the distribution of the load and the reactive supply. the regional reactive power market is composed of a reactive energy market based on marginal pricing and a reactive capacity market based on a reactive regulating capacity payment. the cases in section iv, based on the market organization proposals and the reactive bid structure previously presented, performed on a five - bus system and the ieee 14 bus system, are used to analysis the effects of active bid, voltage control and power factor on the reactive marginal price
本文首先回顧了電力市場發展的歷史和現狀;然後對市場中的定價方法和無功輔助服務的內容及特點進行了總結,並介紹了一些國家的無功輔助服務市場模式和交易方法;接著立足我國國情,提出了單邊開放電力市場下的無功市場框架:即根據負荷和無功源的分佈特點建立區域無功市場,各區域無功市場又由相應的無功電量市場和無功容量市場組成;並提出了該無功市場模式下的機組報價模型和基於報價的以系統總購電費用最小為目標的無功電價計算方法;最後用一個5節點系統和ieee14節點系統進行了實例分析,初步研究了發電機有功報價、系統電壓控制以及負荷功率因數對無功電價的影響,得出了一些有借鑒意義的結論。Based on the summary of the fruits of the research of the active power factor correction, the pfc system, which adopts cuk power converter circuit and average current mode control scheme, is well studied in this thesis
本文在總結有關有源功率因數校正研究成果的基礎上,針對目前研究的熱點及其發展方向,對單相有源功率因數校正技術作了較為深入的探討,並提出了將升壓型平均電流控制的功率因數校正思想用於cuk型電路拓撲。
