摘要：

In this paper, a feedforward control circuit for buck and buck-derived converters is proposed, analyzed, and tested. Analysis under reasonable approximations shows that excellent regulation that compensates input voltage variations can be achieved, allowing open-loop operation. A test circuit is constructed and subjected to experimental verification. Measurements of AC and DC response under the input voltage variations are performed, exhibiting good agreement with analytical predictions. Deviations from the ideal performance were explained, and future work is suggested to achieve further improvements.
