  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,在調系數0 . 1 m 0 . 5情況下,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,經過整流、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通,滯后橋臂或者零電壓通( _ 0 )或者零電流斷( _ 0 )的軟特性,而低頻逆變器的各個均實現零電壓條件下的通與斷。
  2. 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變流型三相高頻鏈逆變器結構和的復雜性,提出了一種實現簡單而整體優化的vvvf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;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姍調壓協調逆變器輸出電壓,在滿足輸出電壓條件下使諧最小。
  3. These topologies of inverters are composed of two bi - boost dc / dc converters, they are symmetry. so whole circuit turn into four - quadrant converters, we can control every power mosfet on or off. then we can get sine wave with direct current polarization at the left, at the same we also can get sine wave with direct current polarization phase contrast 180 compared of the left at the right

    這類逆變器由左右二個雙向boostdc / dc變換器構成,左右二邊是對稱的,所以整個電路構成了一個四象限變換器,我們可以恰當各功率管的,使左邊的兩象限dc / dc變換器輸出一個帶直流偏置的正弦,使右邊的兩象限dc / dc變換器輸出一個相差180度帶同樣直流偏置的正弦形,這樣,負zl上的電壓是左、右兩個dc / dc變換器電壓的差動輸出,正好可以消掉直流偏置,最終在負r1上得到的就是正弦
  4. The switches of the two - level leg suffer the input voltage and can realize zero - current - switching ( zcs ) in a wide load range, so the igbt can be adopted. the voltage across the output filter is a tl waveforms, which reduces the output filter. the input current of hfb tl converter is nearly a dc current, which reduces the input filter

    復合式全橋三電平變換器不僅可以將管電壓應力減小一半,大大改善輸出濾器工作條件的優勢,還可實現所有管的全負范圍軟,本文詳細分析該變換器的工作原理、參數設計、方案,並進行實驗驗證。
  5. This paper simulates and analyses the torque pulsation because of the modulation frequency and speed variation under ambipolar pulse width modulation ; the influence of snubber circuit, dead time effects, and modulation frequency to igbt pwm inverterbridge is taken into account, too

    本文對雙極性調的無刷直流電動機模擬,分析了轉速和調頻率對轉矩影響;並綜合考慮緩沖電路、死區及頻率對pwm逆變電路中igbt損耗的影響。
