Abstract:

A novel inverter based on the Buck conversion iS presented.Then,a low-frequency mean-value model of the inverter circuit is established to analyze the steady and transient responses of the converter with different classic control methods by means of the classic control theory.The best control method named PD control is finallv achieved.Experimental results show that the presented inverter is of good transient response and robustness, thus validating the correctness of theoretical analysis.

Key words: inverter, Buck conversion, stability, transient response
