Abstract


Modern inverter technology is an important part of power electonic technology. With the development of industrial technology, the demand of power quality is becoming higher and higher and showing diversity in different field. Besides, the rise of wind, solar and other new energy technology offers a wide space for the application of sinusoid inverter.The paper gives a deep research on the principle, classification and circuit topology of inverter at first. The control method and output character of PWM inverter was deeply analyzed. The application of Digital PID algorithm in the close-loop control of sinusoid inverter is presented.Secondly, the paper proposes a solution of sinusoid inverter, and discusses the main circuit based on IPM and the inverter controller based on DSP. The principal and architecher of relevant circuit modules are discussed in detail, and the implementation of the inverter software system is presented.Lastly, through SPWM driving signal output experiment and PWM inverter experiment, the rationality of the whole system design is verified. The experiment result shows that the design of the sinusoid inverter hardware and software is successful.
