Abstract: Une alimentation de puissance a noyau de saturation (17) pour un recepteur de television comprend un reacteur saturable (SR1) ayant un noyau magnetisable (21) et un enroulement (20) situe sur celui-ci. Un courant d'excitation pour le reacteur saturable est developpe a partir d'une source (26) ayant une tension d'entree non regulee. Un flux magnetique est genere dans le noyau magnetisable qui enchaine l'enroulement du reacteur pour developper une tension de sortie a polarite alternative. Un condensateur (c) developpe un courant de circulation qui genere une force de magnetisation dans une section de noyau associee a l'enroulement du reacteur. Un aimant permanent (22) polarise le noyau (21) pour produire une seconde force de magnetisation dans la section de noyau associee. La resultante des deux forces de magnetisation developpe un flux magnetique qui sature sensiblement le materiau magnetisable de la section de noyau associee pendant chaque cycle de la tension de sortie de polarite alternative pour reguler la tension de sortie. La stabilite de la temperature de la tension de sortie sensible a la temperature est obtenue par la resistance de polarisation commandee par la temperature de l'aimant permanent (22).

Abstract: RCA 83,439 A signal suppression component such as a ferrite shield bead includes a cylindrical magnetically permeable member that has a longitudinal passage formed through it. The passage is filled with an elastic silicone rubber material. When the component is placed on a conductor or component lead, the elastic material forms a damping layer between the conductor and the permeable member to prevent audible vibration of the element due to current flow in the conductor. Such a component is especially useful in a line rate deflection circuit and in a resonant retrace power supply circuit.

Abstract: The primary of a transformer with a high leakage inductance is coupled to an unregulated alternating voltage source. The output voltage from a secondary winding is full wave rectified by diodes and filtered by a capacitor to provide a voltage for the audio circuits. The voltage developed in another secondary winding is full wave rectified and is filtered by a capacitor to provide a voltage for the tube grid circuits. A separate winding is used to provide the EHT supply. The output windings are tightly coupled magnetically and their output voltages are controlled by a saturable reactor connected to the tube grid supply winding. This reactor comprises a winding on a magnetically saturable core and coupled to a resonating capacitor. A permanent magnet polarises the core to stabilise the output voltages against temp. effects.
