Abstract :
This paper presents an stability analysis methodology for discrete-time control systems employing linear time-periodic models. This methodology provides a multi-step periodic invariant representation whose characteristic is linear time-invariant. The stability analysis of a full-bridge PFC rectifier is presented in order to demonstrate the proposed methodology. Simulations results are presented to validate the proposed technique.
