Title (EN) SELF-OSCILLATING AMPLIFIER WITH HIGH ORDER LOOP FILTER
(FR) AMPLIFICATEUR AUTO-OSCILLANT À FILTRE DE BOUCLE D'ORDRE ÉLEVÉ
Abstract: front page image
(EN)A self-oscillating amplifier system is disclosed. The system comprises a pulse modulator, a switching power amplification stage and a demodulation filter. Moreover, the system comprises a compensator including a forward filter which is a high order filter including a second order pole pair and a second order zero pair. Hereby it is possible to decrease the phase turn at low frequencies for better stability and increasing the gain of the control loop within the desired bandwidth.
(FR)L’invention concerne un système amplificateur auto-oscillant. Le système comprend un modulateur d'impulsions, un étage d'amplification de puissance à découpage et un filtre de démodulation. De plus, le système comprend un compensateur comprenant un filtre direct qui est un filtre d'ordre élevé comprenant une paire de pôles du second ordre et une paire de zéros du second ordre. Ainsi, il est possible de réduire la rotation de phase aux basses fréquences pour obtenir une meilleure stabilité et augmenter le gain de la boucle de commande dans la largeur de bande souhaitée.
