Abstract[English]
A synchronous average harmonic current controller is used to simultaneously control line load current and switching transformer current for a resonant power converter. The controller takes its feedback input from a current command and a bridge current sensor which measures total current flowing between the bridge switching nodes. The controller is implemented using an inverting switched capacitor filter. The filter switches two capacitors across the output and inverting node of an error amplifier to integrate and compensate current error synchronously over each half of the fundamental period. The superimposed non-modulated common and modulated difference feedback signals apply duty cycle and phase control which reduces the synchronous average error current. As a result of synchronous average current control of the line load and transformer currents, the primary and secondary bridge have a defined voltage relationship which is straightforward to regulate.[French]
Un dispositif de commande de courant harmonique moyen synchrone est utilisé pour commander simultanément un courant de charge de ligne et un courant de transformateur de commutation pour un convertisseur d'alimentation résonant. Le dispositif de commande prend son entrée de rétroaction à partir d'une commande de courant et d'un capteur de courant de pont qui mesure le courant total circulant entre les nœuds de commutation de pont. Le dispositif de commande est mis en œuvre à l'aide d'un filtre à condensateur commuté inverseur. Le filtre commute deux condensateurs à travers le nœud de sortie et d'inversion d'un amplificateur d'erreur pour intégrer et compenser une erreur de courant de manière synchrone sur chaque moitié de la période fondamentale. Les signaux de rétroaction de différence modulés et et non modulés communs superposés appliquent un cycle de service et une commande de phase qui réduit le courant d'erreur moyen synchrone. En raison d'une commande de courant moyen synchrone de la charge de ligne et des courants de transformateur, le pont primaire et le pont secondaire ont une relation de tension définie qui est directe à réguler.
