Research on One-Cycle control for buck converter

摘要

One-Cycle control is a nonlinear control technique based on the integral of a switching variable in order to force its average value to be equal to some control reference. It is firmness for power disturbance, but infirmness for load disturbance. In this paper an improvement solution is proposed in order that one-cycle controlled buck converter operating in DCM does work properly even under load widely varied conditions. The theoretical predictions are confirmed by the results of suitable numerical simulations.
