Abstract

UNA FUENTE DE ALIMENTACION DEL TIPO DE CONMUTACION COMPRENDE CIRCUITERIA DE NEUTRALIZACION PARA CONTRARRESTAR EL FLUJO DE CORRIENTE A LA MASA DEL EQUIPO COMO CONSECUENCIA DE CORRIENTES RF GENERADAS. ESTA CIRCUITERIA DE NEUTRALIZACION INCLUYE UN ARROLLAMIENTO DE TRANSFORMADOR INCORPORADO (136) Y UN CONDENSADOR DE NEUTRALIZACION (138, 139) PARA CONTRARRESTAR Y CANCELAR CORRIENTES DE FUGA ESPECIFICAS. ESTA DISPOSICION PERMITE EL USO DE CONDENSADORES DE FILTRO MAS PEQUEÑOS Y, POR TANTO, REDUCE EL FLUJO DE CORRIENTES DE FUGA DE FRECUENCIA DE LINEA A LA MASA DEL EQUIPO.
