Title (EN) POWER TRANSFER CIRCUIT
(FR) CIRCUIT DE TRANSFERT DE PUISSANCE
Abstract: front page image
(EN)This is a power transfer circuit for transferring power from a d.c. input (11) to a load (12) by way of an air gap (13) in a ferromagnetic core (14), so that there is contactless transfer of energy across the gap. The core includes an input winding (16) whose inductance depends upon the length of the air gap (13), and which inductance determines the resonance frequency of an oscillator including a capacitor (22) connected across the winding (16). The oscillator includes a pair of switching transistors (T1) and (T2) and generator sinusoidal oscillations.
(FR)Un circuit de transfert de puissance pour transferer la puissance d"une entree a courant continu (11) a une charge (12) au moyen d"un entrefer (13) dans un noyau ferro-magnetique (14) de sorte que le transfert d"energie a travers l"espacement se fasse sans contact. Le noyau comprend un enroulement d"entree (16) dont l"inductance depend de la longueur de l"entrefer (13), laquelle inductance determine la frequence de resonance d"un oscillateur comprenant un condensateur (22) connecte a l"enroulement (16). L"oscillateur comprend une paire de transistors de commutation (T1) et (T2) et un generateur d"oscillations sinusoidales.
