Abstract
Amplificateur push-pull comprenant un transformateur de sortie dont le primaire est alimenté par deux montages de transistors en cascade qui sont attaqués par le signal d'entrée devant être amplifié et qui reçoivent la tension d'alimentation d'une source de courant continu. Les transistors qui se trouvent en amont des transistors de sortie des montages en cascade peuvent recevoir du transformateur de sortie 13 et par l'intermédiaire de redresseurs 20, 20' une tension qui est supérieure à la tension d'alimentation délivrée par la source de courant continu 10. Application en particulier aux amplificateurs pushpull dont la source d'alimentation délivre une tension relativement faible.Push-pull amplifier comprising an output transformer whose primary is supplied by two cascaded transistor arrangements which are driven by the input signal to be amplified and which receive the supply voltage from a direct current source. The transistors which are located upstream of the output transistors of the cascade assemblies can receive from the output transformer 13 and via rectifiers 20, 20 'a voltage which is greater than the supply voltage delivered by the current source continuous 10. Application in particular to pushpull amplifiers whose power source delivers a relatively low voltage.
