The envelope-following (EF) simulation of practical dc-dc converters is challenging due to the presence of digital behavior, strong nonlinearity, complex frequency module schemes, and feedback loops. This paper presents a novel EF method for time-domain analysis of dc-dc converters-based upon a numerically robust time-delayed phase condition to track the envelopes of circuit states under a varying...
DC-DC converters form an essential component of modern low-power integrated circuits. This paper presents a novel nonlinear modeling technique for pulse-width modulated (PWM) DC-DC converters for low-power applications. Our enhanced model not only predicts the dc response, but also captures harmonics of arbitrary degrees. The proposed full-order model retains the inductor current as a state variable...
