【 摘 要 】

The paper investigates predictive digital average current control (PDACC) in dc/dc converters using trailing-edgemodulation (TEM). The study is focused on the recurrence duty cycle equation and then stability analysis isperformed. It is demonstrated that average current control using trailing-edge modulation is stable on thewhole range of the duty cycle and thus design problems are highly reduced. The analysis is carried out ina general manner, independent of converter topology and therefore the results can then be easily appliedfor a certain converter (buck, boost, buck-boost, etc.). The theoretical considerations are confirmed fora boost converter first using the MATLAB program based on state-space equations and finally with the CASPOCcircuit simulation package.
