Abstract :
At present, the controller of inverters based on the load of resistance will produce the distortion of output voltage, make the system not to work because of losing the stability at worst, the reason which cause these is that the designer didn´t consider adequately the uncertainty of load and input voltage. In order to solve this problem, this paper model the single-phase inverters with full-bridge converter, get a robust stability condition which feedback controller should meet on this model based on the theory of H∞, provide the foundation for judging the robust stability of feedback controller of a single-phase inverters with full-bridge converter.
