This paper mainly discusses the design of compensation networks for switching converters in frequency domain. Compensation networks of voltage mode are made for nonideal Buck converter. The transfer function of the networks is analyzed with MATLAB, and then the circuit model is verified with simulink. Comparing the outcomes of open loop sys tem and closed-loop system with compensation networks, the results turned out to be in accordance with the theoretical analysis. This paper provids reference to loop circuit design of switching converter.
