Abstract

LA PRESENTE INVENCION SE REFIERE A UN GENERADOR DE CALOR POR ALTA FRECUENCIA QUE COMPRENDE UN AMPLIFICADOR (AP) DE TUBO ELECTRONICO CUYA SALIDA ESTA CONECTADA A UN CIRCUITO RESONANTE (RE) ACOPLADO ELECTROMAGNETICAMENTE A UNA PIEZA A CALENTAR, Y UN OSCILADOR DE FRECUENCIA CONTROLADA (VCO). EL OSCILADOR (VCO) EMITE UNA SEÑAL DE ALTA FRECUENCIA EN LA ENTRADA DEL AMPLIFICADOR (AP). COMPRENDE TAMBIEN UN MEDIO PARA MEDIR EL DESFASE ENTRE LA CORRIENTE PROPORCIONADA AL CIRCUITO RESONANTE (RE) Y LA TENSION EN SUS BORNES Y PARA MODIFICAR LA FRECUENCIA DEL OSCILADOR (VCO) EN FUNCION DE ESTE DESFASE. APLICACION EN PARTICULAR EN LOS DISPOSITIVOS DE CALENTAMIENTO POR INDUCCION ELECTROMAGNETICA, POR PERDIDAS DIELECTRICAS O POR PLASMA.
