  1. 1 m 0. 5, the phase - shifted angle 6 is controlled in term of sine law which makes the magnitude of resonant voltage track a reference sine voltage, and the resonant voltage is rectified, filtered, inverted and then the better sine - voltage output is obtained, theoretical analysis and experimental results show that for the resistive load and inductive load, the switches of leading leg of the phase - shift - controlled circuit are always turned on at zvs, and ones of lagging leg are turned on at zvs ( < 0 ) or turned off at zcs ( ( > 0 ), moreover, all switches in the low - frequency inverter are always turned on and off at zvs, the measured circuit efficiency for rated load reaches up to 88 %

    從功率單向流動角度出發,提出了一種lcc諧振型恆頻移相單相高頻鏈逆變電路拓撲,調制系數0 . 1 m 0 . 5情況下,控制移相角按正弦規律變化,使諧振電壓脈沖列的幅值追蹤參考正弦電壓信號,經過流、濾、低頻逆變,從而獲得正弦度較好的輸出電壓。理論分析和實驗結果證明對于阻性負或阻感性負,移相全橋具有超前橋臂零電壓開通,滯后橋臂或者零電壓開通( _ 0 )或者零電流關斷( _ 0 )的軟開關特性,而低頻逆變器的各個開關均實零電壓條件下的開通與關斷。
  2. He finds the pitch range after calculated the three important parameters through the bladed for windows software, then presents an optimized control strategy that regulate the pitch angle in terms of the wind speed. it must control the output power because the variational output power brings the variational loads. he confirms and optimizes the control strategy that the output power is the control target, the output power is divided into three parts

    將功率作為系統控制的目標,將功率分成三段進行控制,低風速區,荷是有限的,以功率最大化作為控制目標;額定風速附近,由於處升力曲線斜率的變化點,功率變化較大,應盡快調槳距角進入失速區工作,減少荷的動,該額定風速區的上下工作點要通過場試驗的手段來確定;額定風速以上,使功率維持額定輸出,減少功率動,並通過bladed軟體的模擬計算對控制策略進行了驗證。
  3. Due to the complexity of the structure and control of cycloconverter - type three - phase hf link inverter for soft - switching based on phase - shift - controlled full - bridge mode, a simple and optimized vvvf control strategy is proposed. this control strategy includes : produced pwm by space voltage vector ( svm ) and equivalent carrier frequency fe = 1 / te are introduced into the pdm control of the cycloconverter ; softened equivalent pwm wave is generated at the notches of hf voltage pulses ; the harmonious control between regulating pulse width by phase - shifted angle and regulating voltage of equivalent pwm is to minimize the harmonics content of output voltage of the inverter

    西安理工大學博士學位論文針對這種前級移相全橋軟開關周變流型三相高頻鏈逆變器結構和控制的復雜性,提出了一種實簡單而體優化的vvvf控制策略:將空間電壓矢量產生p姍的方法svm和等效頻率fe = 1 / te引入到周變流器的pdm控制;按高頻電壓脈沖前後沿軟化等效p翎;用移相調節高頻脈沖寬度和等效p姍調壓協調控制逆變器輸出電壓,滿足輸出電壓條件下使諧最小。
  4. Based on the analysis of commercial banks " current concept about fund management, this paper brings forward that fund management is the main - string in its operation, and that the concept of fund management, including security and profitability, is extended from current " forrying fund " to the management of the fund cost and fund risk the paper comprehensively discusses the principle of fund management, the management of fund costs, the tactics of management about fund liquidity, the measures of management about fund risks and how to solve the problems on interest risk in the period of frequent interest fluctuation. the paper puts forward ideas on how to improve the fund management. the security, liquidity and profitability of the fund, which are both contradictory and integrated with one another, are internal factors of fund management. fund liquidity is traditional core question. commercial banks face with a number of risks of witch credit risk is the greatest one because our country has adjusted interest rates 8 times since 1996, which covered a period of frequent interest fluctuation

    商業銀行面對許多風險,但最大風險是信用風險。由於我國自1996年以來已連續調了8次利率,近幾年是利率動頻繁時期,研究利率的敏感性問題顯得特別重要。要改善資金管理,提高商業銀行的經營水平,就要建立資金管理是商業銀行經營主線的理念,對資金要統一規劃和管理;要改革銀行的體制,建立代企業制度和法人治理結構,體制上為資金管理提供有利的運行平臺;增加改善資金流動性管理所需的貨幣政策工具,擴大資金調控手段;打破貨幣市場的僵化局面,為資金管理創造有利的宏觀環境;續續優化負債結構和負債體設計;增強資金信用風險規避和化解的措施;通過銀行資源合,努力尋找資金的安全投放渠道,最終完成經營模式由傳統型向代型的轉變。
