“…After simplification, the state equations in the charging mode and discharging mode can be described as follows: Since the DC operating point of the BSS-FBC generally contains AC components near the line frequency, the commonly used small-signal analysis method for DC/DC converters is not applicable to this situation. In [75,76], a small-signal modeling method suitable for PWM controlled high power factor AC/DC converters was introduced. According to this method, the control-to-inductor-current transfer function can be derived as follows:…”

“…According to [75][76][77], when ignoring the perturbation on the capacitor voltage ˆo u , the load is a constant voltage source, and by high-frequency approximation, Equation (17) can be simplified to:…”

“…En concreto, la respuesta de la tensión de salida en rectificadores con alto factor de potencia derivados de la topología Boost, una de las implementaciones más frecuentes y la topología en la que se centra la tesis, está fuertemente limitada en frecuencia [36][37], por lo que la búsqueda de métodos que permitan reducir los efectos de las variaciones de carga sobre la tensión de salida del convertidor es un objetivo que ha suscitado un importante esfuerzo investigador en los últimos años [38]- [45].…”

“…Tradicionalmente, este problema ha supuesto que, en la práctica, la frecuencia de cruce del lazo de tensión se sitúe como máximo entre una quinta y una décima parte de la frecuencia de red rectificada. Este imperativo de tener que trabajar con anchos de banda bajos en el lazo de tensión, implica que tanto la impedancia de salida como la respuesta temporal frente a variaciones de carga van a ser pobres [36] [37].…”
