Abstract：In view of the shortcomings of traditional development model in power electronic equipment，such as research and development cycle long，time-consuming for code test. By using the model based design method，developed a 1.5 kW single phase photovoltaic grid connected inverter with deadbeat controller，from the principle of single phase photovoltaic grid connected inverter to achieve the entire system，described the process and model based design method in detail，to show the superiority of the model based design. The results show that the method can significantly enhance the reliability，portability，testability and readability of code，leaving out manual programming controller code，test and verification for code，greatly shorten the development cycle.
