| 摘 要： | 本文重点介绍基于TMS320F2812的静止无功发生器SVG中逆变器的控制信号的实现方法。控制对象是六组由IGBT单管及其反并联的续流二极管构成的三相桥式逆变电路。关键的控制信号SPWM的脉冲宽度采用中值规则采样法来求取。本装置利用TI公司生产的数字信号处理器TMS320F2812DSP以纯软件的方法来产生SPWM波形．该方法具有控制精度高和实时性好等特点。

| Abstract: | This paper introduces mostly the method of generating control signal of SVG's inverter base on TMS320F2812.The object is the inverter circuit of three-phase bridge,which is composed of six groupes of IGBT and its shunt-wound diode reversed.The pulse width of the key control signal SPWM is acquired by the sampling method based on median rule.The device use TMS320F2812 DSP which mand by TI to generate the SPWM wave by software method, whichischaracteristicofhighcontrolprecisionandgoodrealtimeperformance. |
