Rel\u00e9s de estado s\u00f3lido<\/span><\/a><\/span> son componentes clave en los sistemas de control de temperatura (como los sistemas de climatizaci\u00f3n, los sistemas el\u00e9ctricos de calentamiento de agua, las saunas, las m\u00e1quinas de moldeo por inyecci\u00f3n, etc.) que se utilizan para encender y apagar de forma r\u00e1pida y precisa los elementos calefactores, logrando as\u00ed un control preciso de la temperatura.<\/span><\/p>

Todos los rel\u00e9s de estado s\u00f3lido utilizan principalmente dos m\u00e9todos de control: el control por paso por cero y el control de activaci\u00f3n aleatoria.<\/span><\/p>

Un SSR de cruce por cero no se activa inmediatamente tras recibir una se\u00f1al de control; espera a que la corriente alterna cruce por cero antes de conectar la carga. Estos SSR cuentan con un circuito integrado de detecci\u00f3n de tensi\u00f3n de cruce por cero (como se muestra en rojo en el diagrama siguiente).<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

El funcionamiento del rel\u00e9 de estado s\u00f3lido de paso por cero es el siguiente: cuando se recibe una se\u00f1al de entrada de control, la salida del rel\u00e9 de estado s\u00f3lido no se activa inmediatamente, sino que espera a que la tensi\u00f3n sinusoidal de CA descienda hasta el punto de paso por cero antes de activar el circuito de salida. Cuando se retira la se\u00f1al de entrada, el rel\u00e9 de estado s\u00f3lido se desactivar\u00e1 autom\u00e1ticamente en el siguiente punto de paso por cero.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. Menor ruido el\u00e9ctrico<\/b>:<\/span> Dado que los rel\u00e9s de estado s\u00f3lido (SSR) de cruce por cero se activan a una tensi\u00f3n cercana a cero, se reducen los cambios bruscos en la tensi\u00f3n de carga. Esto ayuda a minimizar las interferencias electromagn\u00e9ticas (EMI).<\/span><\/li>
  2. Corriente de arranque reducida para numerosas cargas resistivas<\/b>: Conectar una carga resistiva cerca del punto de paso por cero de la tensi\u00f3n reduce la corriente de arranque inicial en comparaci\u00f3n con encenderla en el punto m\u00e1ximo de la onda de CA. De este modo se evita el impacto de los picos de tensi\u00f3n y corriente en la vida \u00fatil del calentador.<\/span><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    El principal inconveniente es que los rel\u00e9s de estado s\u00f3lido (SSR) no pueden activarse en cualquier punto de una forma de onda de corriente alterna.<\/span><\/p>

    Tras recibir una se\u00f1al de control, es posible que tenga que esperar al siguiente paso por cero adecuado.<\/span><\/p>

    En las aplicaciones t\u00edpicas de calefacci\u00f3n, este retraso suele ser insignificante. Sin embargo, en el caso de algunas cargas que requieren una conexi\u00f3n el\u00e9ctrica inmediata, este retraso puede suponer una desventaja significativa.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Cuando se aplica una tensi\u00f3n de control al terminal de control, el terminal de carga entra inmediatamente en conducci\u00f3n. En otras palabras, tras aplicar una se\u00f1al de control, el terminal de carga puede entrar en conducci\u00f3n en pr\u00e1cticamente cualquier punto de la forma de onda de CA.<\/span><\/p>

    Por ejemplo, si se aplica una se\u00f1al de control cuando la tensi\u00f3n de CA se encuentra cerca de su valor m\u00e1ximo, el rel\u00e9 de estado s\u00f3lido de activaci\u00f3n aleatoria se activar\u00e1 en ese momento sin esperar al siguiente punto de paso por cero.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
