Zusammenfassung:A horizontal deflection amplifying apparatus for use in an automatic main power supply such as that for a cathode ray tube is provided. The apparatus uses a microprocessor for the connection of capacitors to a horizontal deflection coil (yoke coil) by controlling the switching operation of relay switches. To prevent the drive transistor of the deflection coil driver from being destroyed or the horizontal deflection coil from being damaged due to excess current, the capacitors are connected or disconnected while the power supply voltage is off (i.e., at a 0V state) and the supply voltage is then re-applied. Thus, the horizontal deflection amplifying apparatus can be safely driven. APARATO AMPLIFICADOR DE DESVIACION HORIZONTAL PARA USO EN UNA FUENTE DE ALIMENTACION PRINCIPAL AUTOMATICA TAL COMO LA DE UN TUBO DE RAYOS CATODICOS. EL APARATO UTILIZA UN MICROPROCESADOR PARA LA CONEXION DE CONDENSADORES A UNA BOBINA DE DESVIACION HORIZONTAL (BOBINA DEL YUGO) CONTROLANDO LA OPERACION DE CONMUTACION DE UNA PLURALIDAD DE INTERRUPTORES DE RELES. PARA IMPEDIR QUE SE DESTRUYA EL TRANSISTOR DEL EXCITADOR DE BOBINA DE DESVIACION O SE DAÑE LA BOBINA DE DESVIACION HORIZONTAL DEBIDO A EXCESOS DE CORRIENTE, SE CONECTAN O SE SEPARAN LOS CONDENSADORES MIENTRAS LA TENSION DE LA FUENTE DE ALIMENTACION ESTA CORTADA (O SEA, EN UN ESTADO DE 0V) Y A CONTINUACION SE VUELVE A APLICAR LA TENSION DE ALIMENTACION. ASI, EL APARATO AMPLIFICADOR DE DESVIACION HORIZONTAL PUEDE EXCITARSE CON SEGURIDAD.
