| Abstract: | Characteristics of inverter in renewable energy utility and how to use hysteresis comparison PWM tracking control are introduced in this paper. Starting from the characteristics of hysreresis comparison control, the principle of hysreresis comparison control and the formula of actual switch frequency are gotten. The simulation shows the presupposition rationality and the correctness of the analysis, it also shows the simplicity of the method and circuit with quick responsibility, low harmonics and fitness for both isolated and grid-connected application. |
