Abstract
CIRCUITO ESTABILIZADOR DE ARCO DE ALTA FRECUENCIA QUE INCLUYE UN OSCILADOR CONTINUO PARA GENERAR UNA ONDA CUADRADA NO SINCRONIZADA. UNA SALIDA DEL OSCILADOR SE INVIERTE Y AMORTIGUA, Y LAS SALIDAS SOSTENIDAS E INVERTIDAS ACTIVAN TRANSISTORES DE EFECTO DE CAMPO ACOPLADOS AL INDUCTOR DE UN TRANSFORMADOR ELEVADOR DE ALTO VOLTAJE. EL CIRCUITO PUEDE TAMBIEN DESCONECTARSE PERIODICAMENTE Y FUNCIONAR SOLO DURANTE INTERVALOS DE TIEMPO SELECCIONADOS.
