full-wave phase control
解釋
全波相位控制-
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。 -
In order to the requirement of the full - bridge shift - phase control it designs the pwm wave engender which bases on epld. the pwm wave engender improves the static precision and dynamic speed of the whole control system
為滿足單相全橋移相逆變器的軟開關工作條件,本文重點開發研究了由epld構成的pwm波形發生器,使得整個控制系統的控制精度和動態響應速度大大提高。
