Abstract

Se alimenta una forma de onda de voltaje rectificado en onda completa, no filtrado (V REC) a una fuente de alimentacion (10) que tiene un dispositivo conmutador (Q1) que opera en estados totalmente conductor y no conductor, y a un circuito de voltaje de referencia (13). Cuando la forma de onda de voltaje rectificado cae por debajo de un nivel de umbral, el circuito de voltaje de referencia excita un circuito de control (12), haciendo de esa manera que el dispositivo conmutador comience a conducir una corriente (I OUT). El dispositivo conmutador continua conduciendo hasta que la forma de onda de voltaje rectificado sobrepasa el nivel de umbral. El voltaje de salida (V OUT) está limitado por la realimentacion resistiva (R6) acoplada desde la salida de la fuente de alimentacion al circuito de voltaje de referencia. El valor de la resistencia en la trayectoria de realimentacion incluye en el nivel de umbral y las amplitudes de pico de los pulsos de corriente conducidos por el dispositivo conmutador.
