由於數位控制中的取樣和計算時間延遲對帶寬的影響, 400Hz 逆變器很難甚至不可
能在輸出電壓上保持低總諧波失真。為了改善性能,我們將展示在處理負載不平衡和
400Hz 逆變器總諧波失真( THD)的方法,特別是針對航空業中的 400Hz 逆變器。
在本報告中,提出了一種基於單極性正弦脈寬調變( SPWM)的新型 400Hz 逆變器
配置,適用於航空工業中的 400Hz 逆變器。
我使用了三個獨立的單相逆變器結合串級環路控制。在控制方案中,對串級環路共
振-死拍控制進行了分析和處理,以簡化傳遞函數。然後分析了所提出系統的穩定性,並
使用數位處理設計控制策略。我的系統在 15kVA、三相、 115V 400Hz 逆變器的測試平臺
系統中進行了測試。我進行了模擬來比較死拍控制和 PI 控制,並比較了共振雙環路電
流-電壓控制與共振雙環路電壓控制。結果顯示,串級環路共振死拍控制在提供精確且快
速的控制方面表現優異,沒有穩定時間,並且在非線性負載下操作令人滿意,電壓偏差
和總諧波失真都相對較小( <2%)。

Due to the influence the time delay for sampling and computation in digital control on the bandwidth of a 400Hz- inverter is difficult and even impossible to maintain low Total Harmonic Distortion in the output voltage with the conventional proportional integral-based double-loop control. To improve the performance, we will show the methods to deal with unbalance load and Total Harmonic Distortion (THD) of the 400Hz-inverter for airplanes.
In this report, a new configuration of 400Hz-inverters based on unipolar Sinusoidal Pulse Width Modulation (SPWM) is proposed for 400-Hz in aerospace industry.
I used three independents single-phase inverters combined with cascade loop control. In the control scheme, the cascade loop Resonant-Deadbeat control have been analyzed and handled to simplify the transfer function. Then, the stability of the proposed system is analyzed and the control strategy is designed with digital process. My system is tested in testbed systems with a 15-kVA, 3-phase, 115-V 400Hz-inverter. I maked simulation to compare Deatbeat control with PI control and Compared Resonant Dual Loop curent-voltage with Resonant Dual Loop voltage. So, the controntributions are cascade loop Resonant Deadbeat excels in providing precise and fast control without settling time and although operation under nonlinear load is satisfactory with relatively small voltage deviation and total harmonic distortion (<2%).
