  3. The factors which influenced the process include the insulator ' s material, structure, the distribution of space electrical field, the way to deal with the surface, the characteristic of voltage waveform, pulse width etc. there are two kinds of theory for the vacuum surface flashover : secondary electron emission avalanche ( seea ) and electron triggered polarization relaxation ( etpr )

    影響該過程的因素包括絕緣材料結構、空間電場分佈、表面處理方法、所加電壓特徵，脈沖寬度等。研究真空表面閃絡過程有兩類理論：二次電子發射崩潰（ seea ）和電子引發極化鬆弛（ etpr ） 。
  4. 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波變流型三相高頻鏈逆變器結構和控制的復雜性，提出了一種實現簡單而整體優化的vvvf控制策略:將空間電壓矢量產生p姍的方法svm和等效載波頻率fe = 1 / te引入到周波變流器的pdm控制;按高頻電壓脈沖前後沿軟化等效p翎波;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，在滿足輸出電壓條件下使諧波最小。
  5.
