tension p\u00e9riodiques de la sortie d&#8217;une alimentation \u00e9lectrique et consistent en des perturbations du signal CA se superposant sur la sortie CC stable. Se mesurant en millivolts (mV), ces ondulations sont un composant synchrone avec la fr\u00e9quence de commutation. Les caract\u00e9ristiques des ondulations varient selon les diff\u00e9rentes alimentations \u00e9lectriques et peuvent \u00eatre dues \u00e0 des choix de conception de l&#8217;alimentation, \u00e0 des performances de filtre de puissance, \u00e0 des variations de charge ou \u00e0 d&#8217;autres perturbations externes.<\/div><div class=\"ace-line ace-line old-record-id-LcCadJynMo2CBFx0xsIcyeiGnyh\">Contrairement aux ondulations, le bruit est un composant \u00e0 haute fr\u00e9quence qui se produit entre des bornes de sortie en tant qu&#8217;interf\u00e9rence al\u00e9atoire et non p\u00e9riodique. Le bruit de l&#8217;alimentation \u00e9lectrique consiste essentiellement en une tension irr\u00e9guli\u00e8re et discontinue ou en des cr\u00eates de courant caus\u00e9es par diverses perturbations
