Abstract
L'invention a pour but de créer un transformateur remédiant aux inconvénients des transformateurs connus et comportant un écran électrostatique entre l'enroulement primaire et l'enroulement secondaire du transformateur, une extrémité de l'écran étant reliée au potentiel de masse, du côté du primaire du point de vue alternatif pour réduire la capacité de couplage entre l'enroulement primaire et l'enroulement secondaire. L'invention a notamment pour but de créer un tel transformateur applicable à un inverseur.
