本文在文献[1]的基础上推导了半桥和全桥逆变器的电压控制理论。详细的分析结果的对称脉宽调制电压控制方法。电压控制技术的推导，从而谐波消除是可能的变频变压三相逆变器电路。利用现代控制理论的思想，在可控硅开关频率的约束下，对半桥逆变技术进行了优化。通过采用所开发的技术，三相逆变器中的变频变压正弦输出是可能的。该方法在交流调速系统中有很好的应用前景。
Theoretical techniques of voltage control for the half-bridge and full-bridge inverters are derived based on the results in [1]. Detailed analytical results for the symmetrical pulsewidth modulation method of voltage control are also presented. Voltage control techniques are derived whereby harmonic elimination is possible in variable-frequency variable-voltage three-phase inverter circuits. The technique for the half-bridge inverter is optimized subject to the constraint of switching frequency of the SCR's, using the concepts of modern control theory. Variable-frequency variable-voltage sinusoidal output in three-phase inverters is possible by employing the techniques developed. The methods show great promise in application to variable-speed ac motor drive systems.
