Title
(EN) MULTI-FREQUENCY TUNING NETWORK SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE RÉSEAU D'ACCORD MULTIFRÉQUENCE
Abstract
(EN) A multi -frequency tuning circuit includes a first branch (302) including a first inductor (306A) and a first capacitor (308A) arranged in series and a second branch (304) including a second inductor (306B) and a second capacitor (308B) arranged in series. The circuit is arranged within a circuitry module configured to be positioned between a source (310) and a load (314), the first branch (302) and the second branch (304) both associated with loads (314), from the source (310), having low impedance frequencies. In order to improve transmitter antenna output power for downhole tools, the tuning circuit creates high impedance at operating frequencies between frequencies corresponding to low impedance.
(FR) Un circuit d'accord multifréquence comporte une première branche (302) comportant une première inductance (306A) et un premier condensateur (308A) agencés en série et une seconde branche (304) comportant une seconde inductance (306B) et un second condensateur (308B) agencés en série. Le circuit est agencé à l'intérieur d'un module de circuit configuré pour être positionné entre une source (310) et une charge (314), la première branche (302) et la seconde branche (304) étant toutes deux associées à des charges (314), à partir de la source (310), présentant de faibles fréquences d'impédance. Afin d'améliorer une puissance de sortie d'antenne d'émetteur-récepteur pour des outils de fond de trou, le circuit d'accord crée une impédance élevée à des fréquences de fonctionnement entre des fréquences correspondant à une faible impédance.
