The study has completed the design of two - phase inverter and made up of the two - phase inverter - motor system for experimental use it is a variable frequency adjustable speed system with a open - loop control of rotational speed, which consists of voltage - controlled oscillator circulating assign device inverter circuit and two - phase induction motor a accurate mathematical model is set based on the whole system, and simulator program of dynamic and steady condition is established, which is used to calculate the dynamic and steady performance by kron and symmetrical coordinate converter by simulator calculation and experimental research with specific parameter of the system, a comparison is made between predicted and experimental characteristics, experimental measurements are shown to compare closely with corresponding theoretical result it is compared with some variable frequency adjus table speed system comprising inverter and single - phase induction motor from the system efficiency torque pulsation and the effect of two - phase inverter capacitance based on the conclusion, harmonic cancellation pulse width modulation control of a two - phase inverter - fed induction - motor drive system is researched, which cancelled the low harmonic and improve the system performance
通過對電機的kron變換和對稱分量變換，建立了系統較精確的數學模型，編制了系統動態及穩態運行的模擬計算程序分別計算系統的動態和穩態性能。通過對系統的具體參數進行了模擬運算和實驗研究，實驗和模擬結果進行比較，說明實驗和理論較為一致，並從系統效率、轉矩脈動及兩相逆變器電容的影響等方面與各種逆變器和單相異步電動機組成的變頻調速系統加以比較。在此基礎上，對兩相逆變器供電-異步電動機系統使用諧波抑制pwm控制進行了研究，由於減少了低次諧波，改善了系統性能。 -
Based on comparison between the parallel - parallel and parallel - serial combination ttfc, a novel two - transistor forward converter with parallel - serial / serial combination is proposed. this converter reduces greatly the current overshoot of the primary side switches and the voltage overshoot of the rectifying diodes. moreover, the size and weight of the converter can also be reduced by interleaving technique and increasing frequency
本文在對並-串型和並-並型雙管正激組合變換器進行了詳細比較研究的基礎上，提出了一種新型並-串串型雙管正激組合變換器，該組合變換器可以大大減小原邊開關管的電流應力和副邊整流電路中二極體的電壓應力；通過交錯控制及提高開關頻率，大大提高了變換器的功率密度。
