摘要

时间延迟存在于大多数电子元件、数字控制器和dsp中。一定的延时值很容易破坏电力控制系统的性能。在中低开关频率的功率控制应用中，这种时间延迟会严重干扰系统动态。在本文中，我们克服了一种基于SVPWM的并网三相电流源逆变器开关模式中时间延迟的影响。实时跟踪系统的时延，估计系统的状态。实验结果清楚地表明，该方法可以补偿时间延迟的影响，提高性能质量。

Time-delay analysis on grid-connected three-phase current source inverter based on SVPWM switching pattern

Time delays exist in most of the electronic components, digital controllers and DSPs. Certain values of time delay can easily corrupt the performance of a power control system. This time delay can strictly disturb the system dynamic in power control applications with low to medium switching frequency. In this paper, we overcome the effect of time delay in an SVPWM based switching pattern for a grid connected three-phase current source inverter. The time delay is tracked in real time and the states of the system are estimated. Our experimental results clearly show that the proposed approach can compensate the effect of the time delay and improve the quality of the performance.
