Dans cet article, nous clarifions pour le convertisseur boost et abaisseur-boost que l'effet d'entraînement n'est pas négligeable pour la réponse en fréquence, et révélons qu'il provoque des caractéristiques inattendues où le décalage de phase ou l'avance de phase apparaît en fonction de la forme de la forme d'onde. du générateur de rampe dans le circuit PWM. Finalement, la marge de phase pour la stabilité change radicalement en fonction de la direction de la pente (normale ou inverse) de la forme d'onde en dents de scie du générateur de rampe, même dans la même configuration de circuit. Pour les effets d'entraînement, nous proposons le modèle d'analyse général et les analysons des convertisseurs boost et buck-boost. En conséquence, nous identifions que les effets d'ondulation sont principalement causés par la variation de la pente et la moyenne de l'ondulation, et révélons que les deux convertisseurs ont des caractéristiques asymétriques pour la direction de la pente de la forme d'onde en dents de scie du générateur de rampe et qu'il y a plus d'avantages pour la stabilité en cas de sens de pente inversé qu'en cas de sens de pente normal. Il a également précisé que l'effet de l'ESR du condensateur de sortie du convertisseur sur la réponse en fréquence est différent selon la forme des formes d'onde en dents de scie. La méthode d'analyse proposée est validée par les expérimentations et les simulations.

Abstract: In this paper we clarify for the boost and the buck-boost converter that the ripple effect is not ignorable for the frequency response, and reveal that it causes the unexpected characteristics where either the phase lag or the phase lead appears depending on the shape of waveform of the ramp generator in the PWM circuit. Eventually the phase margin for the stability drastically changes depending on the slope direction (normal or reverse) of the sawtooth waveform of the ramp generator even in the same circuit configuration. For the ripple effects we propose the general analysis model and analyze them of the boost and the buck-boost converters. As the result we identify that the ripple effects are caused mainly by the variation of the slope and the average of the ripple, and reveal that the both converters have the asymmetric characteristics for the slope direction of the sawtooth waveform of the ramp generator and there is more advantage for the stability in case of the reverse slope direction than in case of the normal one. It also clarified that the effect of ESR of the output capacitor of the converter on the frequency response is different according to the shape of the sawtooth waveforms. The proposed analysis method is validated by the experiments and simulations.
