The modulating functions approach constitutes a simple method for highlighting the accuracy of average models for switch-mode dc-to-dc converters. Due to the low-pass filtering property, such identification technique shows its effectiveness in the case of the evaluation of average models in the case of a Boost converter, at different operating points (different duty ratios). As a primary result of the study, a new analytical model was derived in case the converter is operating at high values of the duty ratio. Such model includes parasitics, represented by the introduction of a loss parameter, whose determination is meaningful for measuring the efficiency of the switch-mode converter.

Abstract
The modulating functions approach constitutes a simple method for highlighting the accuracy of average models for switch-mode dc-to-dc converters. Due to the low-pass filtering property, such identification technique shows its effectiveness in the case of the evaluation of average models in the case of a Boost converter, at different operating points (different duty ratios). As a primary result of the study, a new analytical model was derived in case the converter is operating at high values of the duty ratio. Such model includes parasitics, represented by the introduction of a loss parameter, whose determination is meaningful for measuring the efficiency of the switch-mode converter.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
