基于DSP控制技术的逆变器谐波失真消除

Elimination of Inverter Harmonic Distortion Based on DSP Controlled Technique

对于非线性负载所引起的谐波失真,传统的逆变系统通常采用复杂的大规模无源元件滤波方案来滤除。本文介绍了一种采用DSP控制的逆变器和谐波调节系统的滤波方案,并分析了逆变系统中使用实时数字信号处理控制方法的优点。

Conventional UPS systems operate to protect against such harmonic distortion brought by nonlinear load using complex filtering schemes, often employing large passive components. This paper presents a DSP controlled UPS inverter and harmonic conditioning system, analyzes the advantages of using real time digital signal processing (DSP) control of UPS systems.
