N2 - In this brief, a current ripple recovery (CRR) model is proposed for voltage-mode control converters. By adding a duty cycle sample-hold effect, the inductor current ripple can be recovered so that the high-frequency dynamical information in the inductor current compensates for a conventional averaged model. The CRR model can be used to judge the system stability and, more importantly, identify the subharmonic oscillation. These theoretical results are in good agreement with experimental ones, which demonstrates the validity of the CRR model.
