本文研製一個新型三相多階變流器,使用兩個不同電壓的電壓源作為輸入,可在原三階變流器得到四階的輸出電壓。控制技術採用空間向量脈波寬度調變,其控制方式可以得到較高的電壓利用率及較小的總諧波失真。數位控制器使用的是STM32F407ZGT6,其作為控制核心,計算功率開關元件之工作週期,並輸出控制訊號,使三相變流器可以輸出三相電壓。其架構可應用在三相光電發電系統或馬達驅動器上。
本論文中,首先對三相變流器進行分析,並使用MATLAB Simulink軟體進行模擬,驗證電路可行性。最後實際製作三相變流器使其輸出三相電壓並且驅動三相感應馬達。

This thesis develops a novel three-phase multilevel inverter. The inverter uses two different voltage sources as inputs and the fourth-level output voltage is able to obtain in the original three-level inverter. The space vector pulse width modulation is adopted in the control technique, which can achieve higher voltage utilization and smaller total harmonic distortion. The digital controller uses STM32F407ZGT6 as the control core to calculate the duty cycle of the power MOSFET and output the control signal, so that the three-phase inverter can output a three-phase voltage. The architecture of the proposed inverter can be applied to three-phase photovoltaic power generation systems or motor drivers.
In this thesis, firstly the three-phase inverter is analyzed and simulated with MATLAB Simulink software to verify the feasibility of the circuit. Finally, the three-phase inverter is implemented to output three-phase voltage and drive three-phase induction motors.
