摘要

研究了三开关增量逆变器的矢量控制原理。将确定性和随机两种形式的矢量脉宽调制(PWM)技术与传统的正弦脉宽调制策略进行了比较。通过计算机模拟和实验室模型的实验研究，证明了delta逆变器的工作效率得到了提高。该研究证实了矢量PWM技术相对于正弦PWM策略在增量逆变器中的优越性。然而，逆变器的工作特性的改善并不像桥式逆变器那样显著。随机版本的矢量PWM技术比确定性版本的输出电压和电流的谐波曲线要好得多。

Vector control of delta inverter

The principle of vector control was investigated for a three-switch delta inverter. The vector pulse width modulation (PWM) techniques, both in the deterministic and random versions, were compared with the traditional sinusoidal PWM strategy. The achieved enhancement of the operation of the delta inverter has been documented by results of computer simulations and an experimental investigation of a laboratory model. The study confirmed the superiority of the vector PWM techniques over the sinusoidal PWM strategy for a delta inverter. However, the improvement in the operating characteristics of the inverter is not as significant as that witnessed in bridge inverters. The random version of the vector PWM technique results in radically better harmonic profiles of the output voltage and current than those with the deterministic version.<>
