Abstract

Un circuito convertidor de potencia incluye un circuito de control configurado para generar una señal de excitación con el fin de hacer que un interruptor semiconductor sea conductor y no conductor para generar una tensión de bus a través de un condensador de bus. El circuito de control ajusta un período de funcionamiento mínimo de la señal de excitación a un primer valor cuando una potencia de salida del circuito convertidor de potencia es mayor que un primer umbral y a un segundo valor cuando la potencia de salida es menor que un segundo umbral. El circuito de control puede comprender un comparador que genera la señal de excitación en respuesta a una tensión de detección y una tensión umbral. Durante el funcionamiento en un modo en espera, el circuito de control puede ajustar una amplitud de la tensión umbral basándose en una amplitud instantánea de una tensión de línea de corriente alterna recibida por el circuito convertidor de potencia, de modo que una corriente de entrada extraída por el circuito convertidor de potencia sea sinusoidal.
