英文摘要：

The output voltage differential coefficient and one cycle control （OVDC-OCC） method for DC/DC Converter was proposed. The operation theory was described, and then the small signal model of the OVDC-OCC controlled Buck converter was derived. Frequency-domain simulation was performed on the traditional voltage controlled and new feedback controlled Buck converter, the simulation results were analysed by contrast, and the experimental results was given. The simulation and experimental results show that the OVDC-OCC controlled Buck converter has better dynamic load performance and better capability to reduce the influence of the input voltage disturbance than the traditional voltage controlled Buck converter.
